Integrity verification

Integrity verification is the process of ensuring that data or information remains unchanged and trustworthy from its origin to its destination. It involves checking that the data hasn't been tampered with, corrupted, or altered during transmission or storage. Methods like digital signatures, checksum, or hash functions are used to compare the current state of the data with its original form. If the checks match, the data is considered intact and authentic. This process is vital for maintaining security, accuracy, and trustworthiness in digital communications and storage systems.
