Dynamic update system and dynamic update method

A dynamic update method comprising:

• receiving biometric information of a user and converting the biometric information into biometric data;
• determining whether the biometric data matches registered user data;
• determining whether to perform a dynamic update based on spatial information and time information in response to the biometric data matching the registered user data;
• and
• performing dynamic update based on a result of determining whether to perform the dynamic update,
• wherein the spatial information is based on a first amount of overlap amongst the registered user data and a second amount of overlap between the biometric data and the registered user data such that a higher first amount of overlap is during the dynamic update, the higher priority for dynamic update for the biometric data is set.

A dynamic update system comprising:

• a storage;
• and
• processing circuitry configured to
• receive biometric information of a user in real time and convert the biometric information into biometric data;
• use the biometric data for dynamic updating;
• and
• back up stored data for the dynamic updating in the storage,
• wherein the processing circuitry is further configured to
• determine whether to perform using the biometric data for the dynamic updating based on spatial information and time information, and
• perform dynamic updating,
• wherein the storage is configured to temporarily store the biometric data as temporarily stored biometric data used for the dynamic updating, and
• wherein the spatial information is based on a first amount of spatial overlap amongst previously registered data and a second amount of overlap between the biometric data and the previously registered data such that a higher first amount of overlap is during the dynamic update, the higher priority for dynamic update for the biometric data is set.
