A computer-driven application to verify a user during a log-in procedure, comprising:

• a) a data extraction module which extracts and stores pre-determined data from a personal electronic device of a user;
• b) a random data module, which stores random data sets originating from sources other than said user and analogous to the pre-determined data extracted from said personal device;
• c) a combination generator which combines data from each of said data extraction module and said random data module, to present queries to a user, to which queries said user must identify said user's own data by recognition according to said user's answers to said queries, wherein said questions are presented in at least three cycles, addressing different categories of pre-determined data each time;
• and
• d) an automated output to a computer, wherein when said user correctly answers three cycles of queries in succession, said user's identity is automatically verified for successful log-in to a computer.
