Integrity check
Integrity check is a check for completeness or intactness. Depending on the area of application, this is done, for example, using measured values or checksums .
Applications
- Seals and lead seals are traditional means of integrity testing that are widely used in logistics, for example.
- In data processing , it is used to check data after transmission through space or time and is usually done by comparing it using redundancy such as checksums added to the user data. Digital signatures are particularly sophisticated forms of such checksums. The quantum cryptography also serves this purpose.
- In the case of railway trains, this is usually done by visual inspection based on the presence of a train end signal that was attached to the rear of the last wagon when the train was put together, with vehicle-based testing devices such as one through the entire unit, particularly with a view to improving the route utilization by driving in the mobile block Train running conductor loop should be aimed for.
