What is LGPD and its relevance to ClickCard

The General Data Protection Law, approved in 2018, is legislation that aims to regulate the collection, processing, storage and sharing of personal data of individuals and legal entities. The LGPD establishes clear guidelines for the responsible use of data, ensuring greater control and transparency for data holders.

The LGPD applies to all companies and organizations that collect and process personal data in the Brazilian territory, regardless of size or area of operation. It seeks to ensure that citizens' information is handled in a safe and ethical manner, minimizing the risk of leaks and misuse.

The main objectives of the LGPD and its relevance in the digital age

  • Protection of the rights of data subjects: The LGPD guarantees citizens the right of access, correction, deletion and portability of their personal information, providing greater control over their data.
  • Informed consent: The law establishes that the processing of personal data can only occur with the explicit consent of the holder, except in specific situations provided for in the legislation.
  • Transparency and responsibility: Companies are obliged to inform in a clear and accessible way how the data will be used, assuming responsibility for its protection and security.
  • Fostering an information security culture: The LGPD encourages companies to adopt security measures to prevent security incidents and protect user privacy.

For ClickCard, the LGPD is extremely important, as it handles the data of its users collected during the creation and management of digital business cards. The company needs to comply with the law to ensure the security and privacy of this information.

ClickCard is committed to ensuring the security and confidentiality of its customers' data. In addition to strictly complying with the LGPD, the company is always updating its policies and procedures to comply with the best data protection practices.

The Importance of Data Protection in Digital Business Cards

With the increasing digitalization of business and the adoption of mobile solutions, digital business cards have become a practical and modern way to connect with others. However, it is important to remember that these cards contain sensitive personal and business information that requires proper protection.

ClickCard demonstrates a strong commitment to personal data protection and GDPR compliance. The company establishes a detailed privacy policy that informs users about what data is collected, how it is used and what their rights are in relation to this information.

In addition, ClickCard ensures that all personal data collected is treated with due security and confidentiality.

Check out the examples below:

End-to-End Encryption: ClickCard uses encryption technology to ensure that user data is protected during transmission and storage, preventing unauthorized third parties from gaining access.

Restricted access policy: ClickCard adopts strict data access control measures, ensuring that only authorized persons within the company have access to user information.

Transparency and consent: ClickCard clearly informs users about how their data will be used and requests explicit consent for any further processing that requires authorization.

Ongoing Security Updates : ClickCard is constantly up to date on data security best practices, ensuring that its policies and security measures are always effective.

ClickCard understands that cryptography is one of the main tools to guarantee the security of its users' personal data. Through encryption, information is transformed into an unreadable format during transmission and storage.

Only the authorized recipient, with the proper decryption key, can access and read the data.

The company uses modern encryption algorithms, such as AES, RSA and ECC, to protect user data at every stage of the process, from collection to storage on ClickCard's servers.

This approach ensures that user information is protected from unauthorized access, minimizing the risk of data leaks and breaches.

Cryptography is an encoding technique that transforms readable data into seemingly random, unreadable information called ciphertext. This transformation is performed using complex mathematical algorithms, making the data unreadable to any unauthorized person.

The only way to make the data readable again is by applying the decryption key, which only the authorized recipient has.

ClickCard uses modern and robust algorithms to guarantee the security of its users' data. Some of the main encryption algorithms used include:

  • AES (Advanced Encryption Standard): It is one of the most widely used algorithms today and is considered highly secure. It offers different key sizes (128, 192 or 256 bits) to encrypt the data.
  • RSA (Rivest–Shamir–Adleman): It is a widely used asymmetric encryption algorithm for secure key exchange. It is effective for protecting sensitive information such as encryption keys.
  • ECC (Elliptic Curve Cryptography): Another asymmetric encryption algorithm that offers similar security levels to RSA, but with smaller keys, making it more efficient for mobile devices.
  • AES-256: Another algorithm used by ClickCard to translate its content on the website and application into three languages: English, Portuguese and Spanish.

The choice of these algorithms is based on their reliability and ability to provide a high level of security to protect ClickCard users' data.

The relationship between encryption and GDPR compliance

Encryption plays a crucial role in GDPR compliance, as it is one of the main security measures recommended by legislation to protect users' personal data. The LGPD requires companies to take technical and organizational measures to ensure data security and prevent security incidents.

By using advanced encryption techniques, as ClickCard does, the company demonstrates its commitment to protecting customer data and its compliance with legislation.

Furthermore, encryption helps minimize the impact of any data leaks, since sensitive information will be encrypted and unreadable by unauthorized third parties.

Security Measures Adopted by ClickCard to Protect User Data

ClickCard uses encryption as an essential security layer to protect user data.

Through the application of cryptographic algorithms, data is transformed into an unreadable format during transmission and storage. This means that even if data is intercepted by unauthorized third parties, it cannot be read without proper decryption key.

Security at Different Stages of the Process:

  • Creation of the Digital Business Card: During the creation of the digital business card, ClickCard ensures that the data provided by users is treated with maximum security. Collection is limited to essentials and is done transparently, following LGPD guidelines.
  • Sharing the Digital Card: When a user shares his digital business card with other people, ClickCard ensures that data transmission is protected through secure communication protocols, ensuring that the information is not intercepted or accessed by unauthorized third parties.
  • Digital Card Management: ClickCard implements strict measures to control access to user data. Only authorized people within the company are allowed to access information, ensuring data privacy and security.

ClickCard uses security certificates, such as SSL (Secure Socket Layer) or TLS (Transport Layer Security) , to protect the communication between the application and the company's servers. These certificates encrypt data during transmission, protecting it from interception and ensuring the integrity of the information.

In addition, ClickCard adheres to internationally recognized security standards to protect its users' data. The company is constantly updating to adapt to the best security practices and stay ahead of cyber threats.

Transparency in Data Management

When creating an account on the app, users are clearly informed about what information is collected and how it will be used. This includes data such as name, title, company, email address and phone number, which are essential for creating and managing digital business cards .

Before proceeding with the process, ClickCard requests the users' explicit consent to collect and process their data. This approach aligns with the principles of the LGPD, ensuring that users have full knowledge and control over their personal information.

The LGPD gives users various rights in relation to their personal data, and ClickCard is committed to ensuring that these rights are respected. Among the main rights guaranteed by the legislation are:

  • Right of Access: Users have the right to request information about what personal data ClickCard holds and how it is being used. The company facilitates access to this information through a dedicated communication channel.
  • Right of Rectification: If there is any inaccuracy or outdated personal data, users have the right to request corrections. ClickCard allows users to update their information simply and efficiently.
