User selectable signature
View Patent ↗Computer login may comprise any user-determined submission. A user may select among different devices for input, select the signal content, and as well select the types of signals used for a login signature. Account identification may be inferred by signature rather than explicitly stated. A plurality of discontiguous data blocks in a plurality of files may be employed for validation. The paths to data used in validation may be multifarious, regardless of the prospects for successful authorization.
1. An information processing system which provides secured access, the information processing system comprising:
a program memory;
a data storage memory;
first and second input devices both of which are part of the information processing system and are selectable by a user via the information processing system to allow the user to generate a reference signature that can be compared to a future submitted signature for authentication purposes to allow it to be determined whether access to the information processing system should be granted based on the user selection, wherein at least one of the first and second user selectable input devices is of a type of input device other than a keyboard;
a processing unit operatively interfaced with the program memory, the data storage memory, and the first and second user selectable input devices;
a first set of instructions stored in the program memory that, when executed by the processing unit, allow a user to select at least one signal type, among at least two different user selectable signal types, to be received and stored in the memory, the at least two different signal types being associated with the first or second user selectable input devices;
a second set of instructions stored in the memory that are adapted to be executed after the first set of instructions has been executed, the second set of instructions, when executed by the processing unit, causing
(a) input data of at least one signal type from the user selected one of the first and second input devices to be generated and then recorded in the data storage memory,
(b) a reference signature to be created which comprises in part at least a portion of the input data recorded in the data storage memory, and
(c) the reference signature to be stored in the data storage memory; and
a third set of instructions stored in the program memory that are adapted to be executed after both the first and second sets of instructions have been executed, the third set of instructions, when executed by the processing unit, retrieving the reference signature from the data storage memory and comparing it to a subsequent signature submission signal to allow a determination to be made as to whether or not access to the information processing system should be granted.
2. The information processing system of claim 1 , wherein the information processing system comprises a computer.
3. The information processing system of claim 2 , wherein the computer comprises a desktop computer.
4. The information processing system of claim 1 , wherein the information processing system comprises a hand-held information processing system.
5. The information processing system of claim 1 , wherein the determination is made by accepting the comparison within a designated tolerance of inexactness, thereby authenticating the subsequent signature.
6. The information processing system of claim 1 , wherein at least one of the first and second input devices comprises a pointing device.
7. The information processing system of claim 6 , wherein the pointing device comprises a mouse.
8. The information processing system of claim 1 , wherein at least one of the first and second input devices comprises a keyboard.
9. The information processing system of claim 1 , wherein the first and second input devices comprise a keyboard and a pointing device.
10. The information processing system of claim 9 , wherein the first and second input devices comprise a keyboard and a mouse.
11. The information processing system of claim 1 , wherein the reference signature stored in the data storage memory does not entirely comprise text-character codes.
12. The information processing system of claim 1 , wherein the reference signature stored in the data storage memory comprises at least two user-selected signal types.
13. The information processing system of claim 1 , wherein the signal type comprises a category, among at least two different possible categories, of measurable variable input associated with at least one of the first and second user selectable input devices.
14. The information processing system of claim 1 , wherein the signal type comprises a category of measurable variable input that arises from a user's interaction with a keyboard.
15. The information processing system of claim 1 , wherein the signal type comprises a category of measurable variable input that arises from a user's interaction with a pointing device.
16. The information processing system of claim 15 , wherein the category of measurable variable input arises from a user's interaction with a mouse.
17. The information processing system of claim 1 , wherein at least two different categories of measurable variable input are associated with both of the first and second input devices.
