Embedded line patterns using square-wave linecode

1. An identification document comprising:

personal information associated with the individual; and

line patterns comprising:

a plurality of distinct square-wave lines operable to store, at the identification document, credential data about a person assigned to the identification document; and

wherein a first portion of distinct square-wave lines encodes a first item of credential data and is used to determine whether the personal information corresponds to the first item of credential data.

2. The identification document of claim 1 , further comprising:

an image of an individual; and

wherein a second portion of distinct square-wave lines encodes a second item of credential data and is used to determine whether the image of the individual corresponds to the second item of credential data.

3. The identification document of claim 1 , wherein each line pattern included at the identification document corresponds to an imperceptible square-wave that is embedded at the identification document to encode the credential data associated with the individual.

4. The identification document of claim 1 , wherein the line patterns are formed from square-wave lines that are integrated at particular regions of the identification document to provide a secure means of storing, at the identification document, respective items of credential data.

5. The identification document of claim 4 , wherein each respective item of credential data is associated with a distinct portion of personal information about a person or entity that is assigned to the identification document.

6. The identification document of claim 2 , wherein the first portion of distinct square-wave lines are included at a first region of the identification document and in the image of the individual to depict physical features of the individual.

7. The identification document of claim 6 , wherein the second portion of distinct square-wave lines are included at a second, different region of the identification document with one or more background lines of the identification document.

8. The identification document of claim 2 , wherein the first item of credential data is at least one of:

i) a secure facial template of the person that is assigned to the identification document; or

ii) a web address link that that enables a detector device to obtain a corresponding data record comprising identifying information about the person assigned to the identification document.

9. The identification document of claim 8 , wherein the second item of credential data is a government issued identification number that is linked to the individual or data representing a biometric attribute of the person.

10. A method for generating an identification document, the method comprising:

obtaining personal information about an individual;

determining a mapping of respective items of the personal information to a line pattern that is operable to encode the personal information; and

generating the identification document using the personal information and the line pattern, comprising:

i) embedding, at the identification document, a plurality of distinct square-wave lines that form the line pattern, wherein a first portion of distinct square-wave lines are operable to store a first item of the personal information at the identification document; and

ii) integrating, at the identification document, a second item of the personal information with the first item in response to printing the personal information on the identification document.

11. The method of claim 10 , wherein the first portion of distinct square-wave lines encodes the first item of the personal information at the identification document and the method comprises:

determining whether credential data representing the first item corresponds to the personal information printed on the identification document.

12. The method of claim 11 , wherein:

obtaining the personal information comprises obtaining an image of the individual;

the personal information printed on the identification document includes the image;

the first item of the personal information corresponds to the image; and

the credential data is a secure facial template.

13. The method of claim 12 , wherein determining whether the credential data representing the first item corresponds to the personal information printed on the identification document comprises:

determining whether the secure facial template corresponds to the image printed on the identification document.

14. The method of claim 13 , wherein the first portion of distinct square-wave lines are included at a first region of the identification document and the method comprises:

embedding, at the identification document, a second portion of distinct square-wave lines that form the line pattern,

wherein the second portion of distinct square-wave lines are:

operable to store a third item of the personal information at the identification document; and

are embedded in the image of the individual.

15. The method of claim 10 , wherein the line pattern is an imperceptible square-wave that is embedded at the identification document to encode credential data corresponding to a plurality of items of personal information about the individual.

16. The method of claim 10 , wherein:

the line pattern is formed from square-wave lines that are integrated at particular regions of the identification document to provide a secure means of storing respective items of credential data at the identification document; and

each respective item of credential data is associated with a distinct item of personal information about a person or entity that is assigned to the identification document.

17. A system comprising:

one or more processing devices; and

one or more non-transitory machine-readable storage devices storing instructions that are executable by the one or more processing devices to cause performance of operations comprising:

obtaining personal information about an individual;

determining a mapping of respective items of the personal information to a line pattern that is operable to encode the personal information; and

generating the identification document using the personal information and the line pattern, comprising:

i) embedding, at the identification document, a plurality of distinct square-wave lines that form the line pattern, wherein a first portion of distinct square-wave lines are operable to store a first item of the personal information at the identification document; and

ii) integrating, at the identification document, a second item of the personal information with the first item in response to printing the personal information on the identification document.

18. The system of claim 17 , wherein the first portion of distinct square-wave lines encodes the first item of the personal information at the identification document and the operations further comprises:

determining whether credential data representing the first item corresponds to the personal information printed on the identification document.

19. The system of claim 18 , wherein:

obtaining the personal information comprises obtaining an image of the individual;

the personal information printed on the identification document includes the image;

the first item of the personal information corresponds to the image; and

the credential data is a secure facial template.

20. The system of claim 19 , wherein determining whether the credential data representing the first item corresponds to the personal information printed on the identification document comprises:

determining whether the secure facial template corresponds to the image printed on the identification document.
