Abstract

A method and system for generating a log with location and accelerometer history and verifying the authenticity of the user based on the log. A stroke and capture module captures stroke data from a user. A location identifier module identifies the portable computing device'"'"'s location. An accelerometer determines the portable computing device'"'"'s acceleration. A logging module generates metadata that includes the location and accelerometer history. A verification module receives the location and the accelerometer history. The verification module determines the user'"'"'s mode of transportation based on the accelerometer history. The location and the mode of transportation are compared with information from an authority. If the data matches, the verification authenticates the document.

Claims

1. A method for generating a log of stroke data, comprising:

capturing stroke data from a user that inputs the stroke data into a portable computing device;

identifying a location of the user;

identifying acceleration of the user;

generating a log of stroke data that includes a time of input; and

generating a log of location and accelerometer history.

2. The method of claim 1, further comprising displaying an image of a document and wherein the stroke data is input into the document.

3. The method of claim 1, wherein the log comprises at least one of a unique device identifier, an application version globally unique identifier, a user identifier, a price, a transaction identifier, a previous hash value, a hash of result data, a location identifier and an accelerometer history.

4. The method of claim 1, further comprising the step of generating metadata for the document and metadata for each page in the document, the metadata for each page including an image of the page.

5. A method for verifying a user identity comprising:

receiving metadata for a document, the metadata including stroke data and a first location;

extracting the first location from the metadata;

receiving a second location from an authority;

determining whether the first and second locations match;

responsive to the locations matching, authenticating the document.

6. The method of claim 5, wherein the metadata also includes an accelerometer history and further comprising the steps of:

extracting the accelerometer history from the metadata;

determining a first mode of transportation based on the accelerometer history;

receiving a second mode of transportation from the authority;

determining whether the first and second modes of transportation match; and

responsive to the modes of transportation matching, authenticating the document.

7. The method of claim 5, wherein the metadata also includes a first time of input of the stroke data and further comprising the steps of:

extracting the first time of input from the metadata;

receiving a second time of input from the authority;

determining whether the first and second times of input match; and

responsive to the times matching, authenticating the document.

8. The method of claim 5, wherein responsive to a failure of the locations to match, notifying at least one of the user and the authority of an error.

9. The method of claim 5, wherein the match requires 20% accuracy.

10. The method of claim 5, further comprising routing the document.

11. A method for verifying a user identity comprising:

receiving metadata for a document, the metadata including stroke data and a first location;

extracting the first location from the metadata;

transmitting the location to an authority;

determining whether the first and second locations match;

responsive to the locations matching, receiving verification from the authority.

12. The method of claim 11, wherein the metadata also includes an accelerometer history and further comprising the steps of:

extracting the accelerometer history from the metadata;

determining a first mode of transportation based on the accelerometer history;

transmitting the first mode of transportation to the authority;

determining whether the first and a second mode of transportation match; and

responsive to the modes of transportation matching, receiving verification from the authority.

13. The method of claim 12, further comprising responsive to a failure of the mode of transportations to match, receiving refusal from the authority.

14. The method of claim 11, wherein the metadata also includes a first time of input of the stroke data and further comprising the steps of:

extracting the first time of input from the metadata;

transmitting the first time to the authority;

determining whether the first and a second time of input match; and

responsive to the times matching, receiving verification from the authority.

15. The method of claim 14, further comprising responsive to a failure of the times to match, receiving refusal from the authority

16. The method of claim 11, further comprising authenticating the document.

17. The method of claim 11, further comprising responsive to a failure of the locations to match, receiving refusal from the authority.

18. The method of claim 15, further comprising notifying the user of the refusal.

19. The method of claim 11, wherein the match requires 20% accuracy.

20. The method of claim 11, further comprising routing the document.
