A SYSTEM FOR TESTING SKILLS, FOR INSTANCE FOR DISTANCE LEARNING, METHODS AND COMPUTER PROGRAM PRODUCTS THEREFOR

摘要

A computerized system for testing skills, for example for distance-learning systems, comprises a server (CS) configured for exchanging with at least one client (CU) documents representing test items coming from the server (CS) and responses given to said test items by a subject being tested via the client (CU). The server (CS) comprises a memory (DB) for filing the aforesaid documents exchanged with the client (CU) as documents protected via digital signature. The digital signature has at least one of the following characteristics: - it is generated with a private key of the client (CU) so that the documents are not modifiable by said server (CS ); and - it is affixed on the documents when the latter are not modifiable by the client (CU).
