The agility and convenience of using technology to our advantage to reduce time and costs have made digital signatures a viable alternative for businesses, especially after the pandemic period. In an increasingly competitive market, saving time and resources, increasing productivity, and investing in sustainability have become essential to improving the customer experience. The digital signature market in Brazil is on the rise, and to ensure the authenticity and integrity of this service, we need to better understand what it is, its types, advantages, and how to obtain it.

### What is a digital signature?
A digital signature is a secure technology for authenticating electronic documents for individuals or companies, with legal validity. We live in a scenario where the exchange of information increasingly occurs online, making it necessary to ensure the guarantee, integrity, and authenticity of documents.

Digital signatures use encryption to validate the user's identity and ensure that the document's content has not been altered after signing. This means that the signature has the same legal value as a handwritten signature recognized by a notary. However, digital signatures eliminate the need for sending, storing, archiving, copying, and retrieving paper documents.

It is important to clarify that a digital signature is a type of electronic signature, but not all electronic signatures are digital. What does this mean? It means there are different ways to sign a document electronically, and it is essential to understand them.

### What are the types of digital signatures?
As we’ve seen, a digital signature is a technology to confirm the identity of the signer, whether an individual or a company, and the authenticity of the document. But to understand the types of digital signatures, we need to know the categories of signatures that exist. Currently, there are four types of signatures: handwritten, scanned, electronic, and digital.

### Comparison of Handwritten, Electronic, and Digital Signatures

#### 1 - Handwritten Signature

The most traditional type of authentication, made manually with a pen on physical documents.

- Requires in-person signing with a physical copy of the document.
- Security depends on external factors, such as signature recognition at a notary office.
- Requires physical storage of documents.

##### Used in:
- Signing company contracts.
- Signature recognition at a notary office.
- Formal physical documents.


#### 2 - Electronic Signature

A digitally performed signature, which can have different security levels according to Law 14.063/20 (Simple, Advanced, and Qualified Signatures).

- **Simple**: Identifies the signer using basic evidence (email, password, phone). Suitable for low-risk situations.
- **Advanced**: Uses cryptographic methods and corporate digital certificates (ICP-Brasil or external). Suitable for legal and financial transactions.
- **Qualified**: Requires a digital certificate issued by a Certification Authority (CA) accredited by ICP-Brasil. Provides the highest level of security and detects any modifications made after signing.

##### Used in:
- **Simple**: Reports, receipts, service bookings.
- **Advanced**: Financial transactions, sensitive contracts.
- **Qualified**: Electronic invoices, health records, real estate transactions.


#### 3 - Digital Signature

A type of qualified electronic signature with a high level of security.

### What are the advantages of digital signatures?
While physical signatures can be forged, compromising the validity of your documents, digital signatures, regulated by Provisional Measure No. 2.200-2/2001, provide the necessary security to protect the authenticity and legal validity of your documents with speed, authenticity, and integrity. Here are the five main advantages:

1. Time savings: You save time that would be spent on manual processes, as digital signatures can be completed much faster and more efficiently, speeding up contract closures and negotiations.
2. Cost reduction: By eliminating the need for physical storage space for company documents, you reduce costs associated with paper, printing supplies, transportation, postal services, couriers, notary fees, and more.
3. Security: Digital signatures are protected by encryption, making them the most secure way to validate electronic documents. When using digital certificates issued by a Certification Authority, it is possible to guarantee the user’s identity and the document’s integrity, reducing the risk of fraud and forgery. Therefore, investing in information security is crucial to protect data, clients, and the company’s reputation.
4. Sustainability: By using cloud storage instead of physical paper, we contribute to the environment and avoid the unnecessary use of resources.
5. Organization and mobility: Easy access to documents since they are stored electronically and can be accessed and signed from anywhere with an internet connection.

However, digital signatures eliminate the need for sending, storing, archiving, copying, and retrieving paper documents.

It is important to clarify that a digital signature is a type of electronic signature, but not all electronic signatures are digital. What does this mean? It means there are different ways to sign a document electronically, and it is essential to understand them.

### What are the types of digital signatures?
As we’ve seen, a digital signature is a technology to confirm the identity of the signer, whether an individual or a company, and the authenticity of the document. But to understand the types of digital signatures, we need to know the categories of signatures that exist. Currently, there are four types of signatures: handwritten, scanned, electronic, and digital.

### Comparison of Handwritten, Electronic, and Digital Signatures

#### 1 - Handwritten Signature

The most traditional type of authentication, made manually with a pen on physical documents.

- Requires in-person signing with a physical copy of the document.
- Security depends on external factors, such as signature recognition at a notary office.
- Requires physical storage of documents.

##### Used in:
- Signing company contracts.
- Signature recognition at a notary office.
- Formal physical documents.


#### 2 - Electronic Signature

A digitally performed signature, which can have different security levels according to Law 14.063/20 (Simple, Advanced, and Qualified Signatures).

- **Simple**: Identifies the signer using basic evidence (email, password, phone). Suitable for low-risk situations.
- **Advanced**: Uses cryptographic methods and corporate digital certificates (ICP-Brasil or external). Suitable for legal and financial transactions.
- **Qualified**: Requires a digital certificate issued by a Certification Authority (CA) accredited by ICP-Brasil. Provides the highest level of security and detects any modifications made after signing.

##### Used in:
- **Simple**: Reports, receipts, service bookings.
- **Advanced**: Financial transactions, sensitive contracts.
- **Qualified**: Electronic invoices, health records, real estate transactions.


#### 3 - Digital Signature

A type of qualified electronic signature with a high level of security.

### What are the advantages of digital signatures?
While physical signatures can be forged, compromising the validity of your documents, digital signatures, regulated by Provisional Measure No. 2.200-2/2001, provide the necessary security to protect the authenticity and legal validity of your documents with speed, authenticity, and integrity. Here are the five main advantages:

1. Time savings: You save time that would be spent on manual processes, as digital signatures can be completed much faster and more efficiently, speeding up contract closures and negotiations.
2. Cost reduction: By eliminating the need for physical storage space for company documents, you reduce costs associated with paper, printing supplies, transportation, postal services, couriers, notary fees, and more.
3. Security: Digital signatures are protected by encryption, making them the most secure way to validate electronic documents. When using digital certificates issued by a Certification Authority, it is possible to guarantee the user’s identity and the document’s integrity, reducing the risk of fraud and forgery. Therefore, investing in information security is crucial to protect data, clients, and the company’s reputation.
4. Sustainability: By using cloud storage instead of physical paper, we contribute to the environment and avoid the unnecessary use of resources.
5. Organization and mobility: Easy access to documents since they are stored electronically and can be accessed and signed from anywhere with an internet connection.

### How can I obtain a digital signature?
The LibreCode cooperative offers a digital signature platform called LibreSign, accessible via mobile devices or computers. This platform provides affordable and collaborative solutions, giving clients technological autonomy. Among its main features are the convenience of digitally signing documents and managing them through a Signature Portal compliant with Brazilian legal standards, such as the LGPD (General Data Protection Law) and ICP-Brasil.

LibreSign offers functionalities tailored to the specific needs of each organization. The platform’s solutions are based on open-source software, promoting open access to knowledge and collaboration, ensuring clients’ sovereignty over the technology they use. The service focuses on customization and accessibility, catering to small businesses, large organizations, and government entities alike.

Security breaches can have serious consequences for a brand, including data loss, unauthorized access to confidential information, and damage to a company’s reputation. With this in mind, LibreSign’s greatest advantage is its security effectiveness. The platform implements multi-factor authentication (MFA), which further restricts unauthorized access and ensures that only verified individuals can sign documents. It also allows signer identification through various factors, such as email tokens, SMS, and WhatsApp messages. This method requires users to provide two or more forms of verification before accessing and signing documents, making the signing process much more secure. Each document is encrypted from sending to final signature. This ensures that your information remains secure at every step, meaning only authorized recipients can access and read the document’s content.

Com o mercado cada vez mais competitivo, a economia de tempo e recursos, o aumento da produtividade, o investimento em sustentabilidade, tornam-se essenciais para melhorar a experiência do cliente. O mercado de assinaturas digitais no Brasil está em plena ascensão e para garantir a autenticidade e integridade deste serviço, precisamos entender melhor o que é, quais os tipos, as vantagens e como é possível obter.

### O que é assinatura digital?
A assinatura digital é uma tecnologia segura para a autenticação de documentos eletrônicos para uma pessoa ou empresa com validade jurídica. Vivemos num cenário no qual a troca de informações ocorre cada vez mais online, tornando necessária a garantia, a integridade e autenticidade dos documentos.

A assinatura digital utiliza criptografia para validar a identidade do usuário e para assegurar que o conteúdo do documento não foi alterado após a assinatura. Quer dizer que a assinatura tem o mesmo valor legal de uma assinatura em punho reconhecida em cartório. Entretanto, a assinatura digital elimina o envio, armazenamento, arquivamento, cópia e recuperação de documentos em papel.

É importante explicar que a assinatura digital é um tipo de assinatura eletrônica, mas isso não quer dizer que toda assinatura eletrônica é digital. Mas o que isso quer dizer? Isso significa que existem diferentes formas de assinar um documento eletronicamente e é fundamental conhecê-las.

### Quais os tipos de assinatura digital?
Como vimos, a assinatura digital é uma tecnologia para confirmar a identidade do signatário, seja pessoa ou empresa e autenticidade do documento. Mas para entender os tipos de assinaturas digitais precisamos entender quais as categorias de assinaturas que existem. Atualmente temos quatro tipos de assinaturas - a manuscrita, a digitalizada, a eletrônica e a digital.

#### 1 - Assinatura Manuscrita

Tipo mais tradicional de autenticação, feita manualmente com caneta em documentos físicos.

- Requer assinatura presencial com cópia física do documento.
- Segurança depende de fatores externos, como reconhecimento de firma em cartório.
- Necessidade de armazenamento físico dos documentos.

##### Usado em:
- Assinatura de contratos de empresas.
- Reconhecimento de firma em cartório.
- Documentos físicos formais.


#### 2 - Assinatura Eletrônica

Assinatura realizada digitalmente, podendo ter diferentes níveis de segurança conforme a Lei 14.063/20 (Assinatura Simples, Avançada e Qualificada).

- **Simples**: Identifica o signatário com evidências básicas (e-mail, senha, telefone). Indicada para situações de baixo risco.
- **Avançada**: Usa métodos criptográficos e certificados digitais corporativos (ICP-Brasil ou fora). Apropriada para transações legais e financeiras.
- **Qualificada**: Exige certificado digital emitido por uma AC credenciada na ICP-Brasil. Altíssima segurança, detecta qualquer alteração no documento após a assinatura.

##### Usado em:
- **Simples**: Relatórios, recibos, agendamento de serviços.
- **Avançada**: Transações financeiras, contratos sensíveis.
- **Qualificada**: Notas fiscais eletrônicas, documentos de saúde, registros imobiliários.


#### 3 - Assinatura Digital

- Garante integridade e autenticidade do documento, impedindo alterações sem detecção.

##### Usado em:
- Assinatura de documentos oficiais.
- Transferência de imóveis.
- Emissão de notas fiscais eletrônicas.


### Quais as vantagens da assinatura digital?
Enquanto as assinaturas físicas podem ser falsificadas, comprometendo a validade dos seus documentos, as assinaturas digitais, regulamentadas pela Medida Provisória nº 2.200-2/2001, proporcionam a segurança necessária para proteger a autenticidade e a validade jurídica dos seus documentos com muita rapidez, autenticidade e integridade. Conheça as cinco principais vantagens:

1. Redução de tempo: Você economiza tempo que seria gasto com processos manuais, enquanto que pode realizar uma assinatura digital de maneira muito mais rápida e eficiente, agilizando o fechamento de contratos e negociações.
2. Economia de custos: Ao eliminar a necessidade de manter um espaço físico para guardar todos os documentos da empresa, você reduz custos com compra de papel, tintas para impressão, deslocamento, correios, transportadoras, cartórios, entre outros.
3. Segurança: A assinatura digital é protegida por criptografia, sendo a forma mais segura de validar documentos eletrônicos. Quando utilizamos certificados digitais emitidos por uma Autoridade Certificadora, é possível garantir a identidade do usuário e a integridade do documento, reduzindo riscos de fraudes e falsificações. Por isso, é importante investir em segurança da informação para proteger dados, os clientes e a reputação da empresa.
4. Sustentabilidade: Ao utilizar a nuvem como armazenamento ao invés do papel físico, colaboramos com o meio ambiente e evitamos o uso desnecessário de recursos.
5. Organização e Mobilidade: Facilidade de encontrar e acessar os documentos já que eles são armazenados eletronicamente e podem ser acessados e assinados de qualquer lugar que possua acesso à internet.
