Record number: 1, Textual support number: 1 DEF

The sum of a group of data items, computed when the data are recorded and appended to the group for checking purposes.  3, record 1, English, - checksum

Record number: 1, Textual support number: 1 CONT

The checksum is calculated for a given chunk of data by sequentially combining all the bytes of data with a series of arithmetic or logical operations. After the data is transmitted or stored, a new checksum is calculated in the same way using the(possibly faulty) transmitted or stored data. If the two checksums do not match, an error has occurred, and the data should be transmitted or stored again. Checksums cannot detect all errors, and they cannot be used to correct erroneous data.  4, record 1, English, - checksum

[A] program [that] checks the integrity of an object only when this object is about to be executed.  2, record 2, English, - integrity%20shell

Record number: 2, Textual support number: 1 CONT

The objective of an integrity shell is to drive up the complexity of a corruptive attack by forcing the attacker to make a modification that retains an identical cryptographic checksum.  3, record 2, English, - integrity%20shell

Programas de vigilancia: Ellos detectan actividades que podrían realizarse típicamente por un virus, como la sobreescritura de ficheros o el formateo del disco duro del sistema. En esta técnica, se establecen capas por las que debe pasar cualquier orden de ejecución de un programa. Dentro del caparazón de integridad, se efectúa automáticamente una comprobación de suma y, si se detectan programas infectados, no se permite que se ejecuten.  1, record 2, Spanish, - caparaz%C3%B3n%20de%20integridad

Checksums are used not only to ensure a [corruption-free] transmission, but also to ensure that the file has not been tampered with. When a good checksum algorithm is used, even a tiny change to the file will result in a completely different checksum value.  2, record 5, English, - checksum%20algorithm

Hard drive imaging is used in several major application areas : Forensic imaging or acquisition is the process where the entire drive contents are imaged to a file and checksum values are calculated to verify the integrity(in court cases) of the image file... Data recovery imaging(like forensic imaging) is the process of imaging every single sector on the source drive to another medium from which required files can be retrieved.  4, record 7, English, - imaging
