Method and system for controlling access to a mobile communication terminal
A system for limiting access to a mobile communication terminal comprises user interface for providing an option to select an authentication method to lock the mobile communication terminal; and memory for storing a plurality of lock codes, including image lock codes, inputted into the mobile communication terminal for locking the mobile communication terminal.
1. A method for switching access state of a mobile device from a first state to a second state, the method comprising:
determining first color attributes corresponding to a first image captured by a user using a camera connected to the mobile device;
determining second color attributes corresponding to a lock code comprising a second image stored in a memory of the mobile device, wherein an alphanumeric character and the first image are input in sequence as part of a single lock code;
comparing the first and second color attributes to arrive at a first value; and
switching from the first access state to the second access state, in response to determining that the first value is within a first range, indicating that the first and second images are relatively similar in color, without regard to how sharply focused the first and second images are, and
wherein the lock code is not associated with the mobile device's unique identifier or other data that has been uniquely assigned to the mobile device by a party other than the user and wherein the lock code authentication is performed independent from any communication of the lock code to a base station or entity other than the mobile device.
2. The method of claim 1 , wherein the first state is a lock state and the second state is an unlock state.
3. A method for switching access state of a mobile device from a first state to a second state, the method comprising:
determining first dimension attributes corresponding to a first image of an object captured by a user using a camera connected to the mobile device;
determining second dimension attributes corresponding to a lock code comprising a second image of an object stored in a memory of the mobile device, wherein an alphanumeric character and the first image are input in sequence as part of a single lock code;
comparing the first and second dimension attributes to arrive at a first value; and
switching from the first access state to the second access state, in response to determining that the first value is within a first range, indicating that the first and second images are relatively similar in dimension, without regard to how sharply focused the first and second images are, and
wherein the lock code is not associated with the mobile device's unique identifier or other data that has been uniquely assigned to the mobile device by a party other than the user and wherein the lock code authentication is performed independent from any communication of the lock code to a base station or entity other than the mobile device.
4. The method of claim 3 , wherein the first state is a lock state and the second state is an unlock state.
5. A method for switching access state of a mobile device from a first state to a second state, the method comprising:
determining first dimension and color attributes corresponding to a first image of an object captured by a user using a camera connected to the mobile device;
determining second dimension and color attributes corresponding to a lock code comprising a second image of an object stored in a memory of the mobile device, wherein an alphanumeric character and the first image are input in sequence as part of a single lock code;
comparing the first and second dimension attributes to arrive at a first value;
comparing the first and second color attributes to arrive at a second value; and
switching from the first access state to the second access state, in response to determining that the first value is within a first range and the second value is in a second range, indicating that the first and second images are relatively similar in dimension and color, without regard to how sharply focused the first and second images are,
wherein the lock code is not associated with the mobile device's unique identifier or other data that has been uniquely assigned to the mobile device by a party other than the user and wherein the lock code authentication is performed independent from any communication of the lock code to a base station or entity other than the mobile device.
6. The method of claim 5 , wherein the first state is a lock state and the second state is an unlock state.
7. A security system for switching access state of a mobile device from a first state to a second state, the system comprising:
a logic unit for determining first dimension attributes and first color attributes corresponding to a first image of an object captured by a user using a camera connected to the mobile device;
a logic unit for determining second dimension attributes and second color attributes corresponding to a lock code comprising a second image of an object stored in a memory of the mobile device, wherein an alphanumeric character and the first image are input in sequence as part of a single lock code;
a logic unit for comparing the first dimension attributes with the second dimension attributes, without regard to how sharply focused the first and second images are, to arrive at a first value; and
a logic unit for comparing the first color attributes with the second color attributes, without regard to how sharply focused the first and second images are, to arrive at a second value,
wherein the lock code is not associated with the mobile device's unique identifier or other data that has been uniquely assigned to the mobile device by a party other than the user and wherein the lock code authentication is performed independent from any communication of the lock code to a base station or entity other than the mobile device.
8. The system to claim 7 , further comprising:
a logic unit for switching from the first access state to the second access state, in response to determining that the first value is within a first range and the second value is within a second range.
9. The system of claim 8 , wherein the first value is in the first range when the first and second images are relatively similar in dimension.
10. The system of claim 7 , wherein the second value is in the second range when the first and second images are relatively similar in color.
