Abstract

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.

Claims

1. A computer-implemented process comprising:

receiving user indication of signature input recording;

recording user input signals by type from at least one user-selected device among a plurality of selectable user input devices connected to a single computer,

wherein a signal comprises a set of related software-recognizable data of the same type received from at least one input device,

wherein a signal type comprises a category of measurable variable input associated with at least one user-selectable input device, and

wherein at least one user-selectable input device affords recording a plurality of signal types;

terminating said recording;

storing at least a portion of said recording;

creating a signature based at least in part upon at least a portion of said stored recording; and

storing said signature.

2. The process according to claim 1, wherein said recording comprises signals from a plurality of user-selected devices.

3. The process according to claim 1, further comprising:

receiving user indication to edit said signature;

receiving user selection of at least one signal type from a plurality of signal types associated with at least one user input device of said recording;

editing said stored signature to exclude recorded data of at least one signal type.

4. The process according to claim 1, further comprising:

comparing a subsequent signature submission to at least a portion of said recording,

and accepting said comparison within a predetermined degree of inexactness,

thereby authenticating said subsequent signature.

5. The process according to claim 4, wherein said predetermined degree comprises a user-designated tolerance.

6. The process according to claim 1, further comprising presenting at least a portion of said recording to said user for editing,

wherein said presented recording portion does not comprise text-character codes.

7. The process according to claim 1, wherein at least a portion of said recording comprises at least one signal type comprising signal input from a plurality of devices.

8. The process according to claim 1, further comprising:

dividing a stored signature into distinguishable data portions,

wherein each said distinguishable data portion comprises a key;

linking keys of a signature,

said links determined at least in part by sequential order of user input corresponding to recorded signals;

dividing a plurality of stored signatures into keys;

receiving a first portion of user input data;

accumulating keys of a plurality of signatures based upon matching stored key data to said first portion of user input data;

subsequently, iteratively receiving a plurality of portions of user input data and performing a corresponding authentication step for each portion,

wherein, upon receiving each subsequent portion after said first portion, discarding from further processing previously accumulated keys based upon failure in matching respective key data to said user input data portion; and

whereby continuing said iterative process until completing authentication by matching said last key to corresponding said user input data portion, or by process of elimination determining authentication impossible.

9. The process according to claim 1, wherein said signature comprises signals from at least one category determined by received input after said storing at least a portion of said recording.

10. A computer-implemented process comprising:

commencing signature input recording;

recording user input signals by type from at least one user-selected device among a plurality of selectable user input devices connected to a single computer,

wherein a signal comprises a set of related software-recognizable data of the same type received from at least one input device,

wherein a signal type comprises a category of measurable variable input associated with at least one user-selectable input device, and

wherein at least one user-selectable input device affords recording a plurality of signal types;

terminating said recording;

storing at least a portion of said recording;

creating a signature using said stored recorded user input signals from a plurality of categories of measurable variable input; and

storing said signature.

11. The process according to claim 10, wherein said signature comprises signals from at least one signal type determined by received input after said storing at least a portion of said recording.

12. The process according to claim 10, wherein passively terminating said recording.

13. The process according to claim 10, further comprising:

dividing a stored signature into distinct data portions;

recording and storing a second series of user input signals after storing said signature,

wherein said second series of user input signals are received in incremental portions;

comparing at least one said distinct data portion to at least one said incremental portion;

storing said comparison; and

determining whether to continue receiving and storing a succeeding incremental portion based upon said comparison.

14. The process according to claim 10, further comprising:

comparing a subsequent signature submission to at least a portion of said recording,

and accepting said comparison within a predetermined degree of inexactness,

thereby authenticating said subsequent signature.

15. A computer-implemented method for recording input and creating a signature comprising:

recording user input signals by type from at least one user-selected device among a plurality of selectable user input devices connected to a single computer,

wherein a signal comprises a set of related software-recognizable data of the same type received from at least one input device,

wherein a signal type comprises distinct measurable variable input associated with at least one user-selectable input device, and

wherein recording a plurality of signal types for at least one user-selected device;

terminating said recording;

storing at least a portion of said recording;

creating a signature based at least in part upon at least a portion of said stored recording; and

storing said signature.

16. The method according to claim 15, wherein said signature comprises signals from at least one signal type determined by received input after said storing at least a portion of said recording.

17. The method according to claim 15, wherein creating said signature using recorded signals from a plurality of signal types.

18. The method according to claim 15, further comprising:

dividing a stored signature into distinct data portions; and

incrementally authenticating a second series of user input signals to said signature by comparing said second series of user input signals to their respective distinct data portions of said stored signature.

19. The method according to claim 15, wherein creating said signature from input signals from a plurality of user-selected input devices.

20. The method according to claim 15, wherein said signature comprises in part signals from a pointing device.
