A program is installed by associating the program with an encrypted item of biometric information. The biometric information is encrypted using a private key on the server and associated with the program's execution file on the client. When the program is to be run, the encrypted biometric information is decrypted to obtain reference biometric information. That reference biometric information is compared with currently-obtained biometric information to detect a match. The program is allowed to run into specified and normal way only when the two indicia match. A limited to run may be allowed when the biometrics do not match.
