Capture of alphanumeric passwords from a television remote control reduced key keyboard, uses global dissimulation time stating from end of password capture

摘要

The global dissimulation time is determined as being a duration from the end of capture of the password. Password capture has the following stages: (a) determine a particular dissimulation time; (b) use the keyboard (130) to capture a password character (33); (c) at the end of the dissimulation time mask (132) the last character captured; (d) if need be, capture the following character of the password. Method of capturing an alphanumeric password (133) by means of a reduced keyboard (130) which includes: (a) determine a global dissimulation time; (b) and the end of the time mask the captured characters. A stage is included for executing (147) a user interrupt command for the global dissimulation time so as to mask in an anticipated way the captured characters or the last character. The particular dissimulation time is greater than a running time (T1) for all the characters on the same key of the keyboard (130). .
