Integridad de los Datos (Data Integrity)
La garantía de que los datos permanecen precisos, completos y sin corrupciones durante todo su ciclo de vida.
Para mantener la integridad en tránsito, se usan sumas de comprobación (checksums). Para garantizar el no repudio (quién creó el dato), se utilizan firmas digitales.

Imagina que terminas un puzle y le haces una foto. Si luego alguien cambia una pieza, al mirar la foto sabrás que fue alterado. La integridad de los datos es esa 'foto' matemática que avisa al ordenador si la información ha sido modificada.

❓ Preguntas frecuentes
What is the difference between data integrity and data security?
Data security is the broad practice of protecting data from all threats. Data integrity is one specific pillar of security that ensures the data is accurate and hasn't been altered. Another pillar is confidentiality, which ensures the data is kept secret.
How does a blockchain ensure data integrity?
A blockchain uses cryptography (specifically hashing). Every block contains a mathematical 'fingerprint' of all the data inside it, plus the fingerprint of the previous block. If anyone tries to change past data, all the fingerprints break, instantly alerting the network to the tampering.
What is a checksum?
A checksum is a small-sized block of data derived from another block of digital data. It is used to detect errors that may have been introduced during transmission or storage.
