The output of a cryptographic hash function, also known as a message digest, can provide strong assurances about data integrity, whether changes of the data are accidental (e.g., due to transmission errors) or maliciously introduced. Any modification to the data will likely be detected through a mismatching hash value.
Parchive (a portmanteau of parity archive, and formally known as Parity Volume Set Specification [1] [2]) is an erasure code system that produces par files for checksum verification of data integrity, with the capability to perform data recovery operations that can repair or regenerate corrupted or missing data.

Cyclic codes are not only simple to implement but have the benefit of being particularly well suited for the detection of burst errors: contiguous sequences of erroneous data symbols in messages. This is important because burst errors are common transmission errors in many communication channels , including magnetic and optical storage devices.
A checksum is a small-sized block of data derived from another block of digital data for the purpose of detecting errors that may have been introduced during its transmission or storage. By themselves, checksums are often used to verify data integrity but are not relied upon to verify data authenticity. [1]
Over a number of years, leaked data sets have included email addresses, names, phone numbers, credit card and bank information, medical records and additional personal information.
Open Source Tripwire is a free software security and data integrity tool for monitoring and alerting on specific file change(s) on a range of systems [2] [3] originally developed by Eugene H. Spafford and Gene Kim. [4] The project is based on code originally contributed by Tripwire, Inc. in 2000.
