METHOD AND APPARATUS FOR SAFE STORAGE AND SAFE READING OF USEFUL DATA Russian patent published in 2012 - IPC G06F21/00 G06F12/14 G07C5/00 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering. The method for safe storage of useful data in a digital tachograph, wherein useful data are stored in at least one data unit in at least a given logic data region; at least one data unit is, respectively, associated with a data unit identification code which includes, in the corresponding given data region, a unique uniqueness marker, a unique data region identification code for the given data region, in which the corresponding data unit is stored, and a logic position for the corresponding data unit inside the corresponding given data region, and the data unit identification code is stored; for useful data and the matched data unit identification code, the control data unit value is determined and stored; data region information is associated with the corresponding given data region and then securely or safely stored.

EFFECT: shorter time to be used to protect integrity.
