Abstract

A device, system, and method are directed towards facilitating a registration of a user for a network service. In one embodiment, a server receives, from a user at a client device, user information including at least one text block. The server analyzes the text block to determine an authenticity value of the user information. The analysis may be based on the length of a lexicon of the text block, the size of a word such as the longest word in the text block, or the number of clauses in the text block. The analysis may be further based on expected values determined by such values in authentic text blocks of a similar nature. Based on the authenticity value, the system may allow the user to access the network service, disallow access to the network, allow conditional access, queue the registration application for further review, or take other actions.

Claims

1. A method for employing at least one network device to provide access to a network service for a user, wherein the network device performs actions, comprising:

receiving, from a user at a client device, user information comprising at least one text block that includes registration information that further includes at least one of biographical information, interests information, social information, political information, or opinion information;

determining a lexicon from the at least one text block, wherein the lexicon includes a set of at least one unique word that is a result of an exclusion in the at least one text block of at least one of an alphanumeric character, another word and punctuation;

determining an authenticity value based on combining units of merits and demerits, wherein the authenticity value is further based on at least one of a length of the lexicon derived from the at least one text block, a length of at least one word in the at least one text block, or a number of clauses in the at least one text block;

selectively designating the user information as authentic based on a relationship between the authenticity value and a threshold value; and

if the user information is designated as authentic, allowing the user to access the network service.

2. The method of claim 1, further comprising:

designating the user information as inauthentic based on the authenticity value; and

if the user information is designated as inauthentic, preventing the user from accessing the network service.

3. The method of claim 1, further comprising, based on the authenticity value, selectively performing a human-based filtering.

4. The method of claim 1, wherein the authenticity value is based on at least two of a length of a lexicon derived from the at least one text block, a length of at least one word in the at least one text block, or a number of clauses in the at least one text block.

5. The method of claim 1, wherein the authenticity value is based on a relationship between a length of a lexicon derived from the at least one text block and a length of the at least one text block.

6. The method of claim 5, wherein the length of the lexicon is based on a number of characters in the lexicon and the length of the at least one text block is based on a number of characters in the at least one text block.

7. The method of claim 1, wherein the authenticity value is based on a difference between the longest word derived from the at least one text block and a threshold longest word size.

8. The method of claim 1, further comprising selectively associating the user with another user based on the at least one text block.

9. The method of claim 1, further comprising:

prior to allowing the user to access the network service, determining a second authenticity value corresponding to the user; and

selectively preventing the user from accessing the network service, based on the second authenticity value.

10. The method of claim 1, wherein the network device includes a storage device containing program logic to perform the method of claim 1.

11. A server device for providing access to a network service by a computing device, comprising:

a transceiver device for sending and receiving information including a text block to the computing device, wherein the text block includes registration information that further includes at least one of biographical information, interests information, social information, political information, or opinion information; and

a processor device that executes a registration manager application to enable actions, including;

determining a lexicon from the text block, wherein the lexicon includes a set of at least one unique word that is a result of an exclusion in the text block of at least one of an alphanumeric character, another word and punctuation;

determining a likelihood of authenticity of the text block based on combining units of merits and demerits, wherein the likelihood of authenticity is further based on at least one of a length of the lexicon derived from the text block, a length of at least one word from the text block, or a number of clauses in the text block; and

selectively allowing access to the network service based on the likelihood of authenticity.

12. The system of claim 11, wherein determining the likelihood of authenticity is based on the length of the lexicon derived from the text block and at least one of the length of at least one word from the text block or the number of clauses in the text block.

13. The system of claim 11, wherein the actions further comprise selectively, based on the likelihood of authenticity, performing a human-based determination of authenticity.

14. A system for providing access by a user to a network service, comprising:

a network device that is operative to perform actions, including;

determining a lexicon from at least one text block, wherein the lexicon includes a set of at least one unique word that is a result of an exclusion in the at least one text block of at least one of an alphanumeric character, another word and punctuation, wherein the text block includes registration information that further includes at least one of biographical information, interests information, social information, political information, or opinion information;

determining a likelihood of authenticity for the user based on combining units of merits and demerits, wherein the likelihood of authenticity is further based on content of the at least one text block;

conditionally allowing access to the network service by the user, based on the determined likelihood of authenticity; and

associating the user corresponding to the at least one text block with other users, based on the content of the at least one text block.

15. The system of claim 14, wherein determining the likelihood of authenticity includes determining a first value based on a first characteristic of the content of the text block, and a second value based on a second characteristic of the content of the text block, and combines the first value and second value.

16. The system of claim 14, wherein determining the likelihood of authenticity further includes determining-the likelihood of authenticity based on a length of the lexicon of the text.

17. The system of claim 14, wherein determining the likelihood of authenticity is based on a length of at least one word in the text block.

18. The system of claim 14, wherein determining, the likelihood of authenticity employs at least one metric derived from authentic text blocks received from prior users.
