Abstract

A first user'"'"'s trust level with regard to a second user can be determined by providing questions to the second user, with the questions based on a previously-collected knowledge base including information about the first user. The information about the first user may be partitioned into levels of trust, and the second user'"'"'s responses to the questions may be evaluated to determine which level of trust the second user is entitled to. The knowledge base may be assembled by prompting the first user for information and/or by scanning or otherwise collecting already-existing data about the first user. The knowledge base and/or trust assessment may be distributed across a network, and in some embodiments the knowledge base or parts thereof is distributed to other users according to the trust level of those users.

Claims

a non-transitory computer-readable media having a first knowledge base and a second knowledge base different from the first knowledge base stored thereon;

a computing device having a processor in communication with the knowledge bases, the computing device configured to;

receive a request to establish a relationship between a target user and a second user;

access trust assessment data including data associated with the target user based on the relationship between the target user and the second user and a plurality of data items where each data item is associated with a trust level, wherein the trust assessment data is selected from either the first knowledge base or the second knowledge base according to the relationship;

interrogate the second user, including presenting, to the second user, a plurality of trust assessment questions to the second user, the plurality of trust assessment questions including at least one trust assessment question based on the trust assessment data where the at least one trust assessment question is based on the relationship between the target user and the second user;

receive response data from the second user during the interrogation;

score the second user'"'"'s response to each of the plurality of questions by comparing the response for each question to the trust assessment data corresponding to that question;

aggregate the scores;

assign a trust level to the second user based on the aggregated scores;

generate trust assessment result data based on the interrogation results, wherein the computing device is configured to score, aggregate, and assign a trust level during generation of the trust assessment result data; and

store the trust assessment result data.

2. The system as set forth in claim 1, wherein the trust assessment data includes a plurality of data items, each data item associated with a trust level, the computing device further configured to:

receive response data from the second user during the interrogation;

determine the extent to which the response data matches at least one data item when generating trust assessment result data; and

assign a trust level to the second user based on a highest trust level associated with the at least one matched data item.

3. The system as set forth in claim 1, wherein the trust assessment data includes a plurality of data items, each data item associated with a trust level, wherein the computing device is further configured to:

provide a plurality of trust assessment questions to the second user and receive response data from the second user during interrogation;

score the second user'"'"'s response to each of the plurality of questions by comparing the response for each question to the trust assessment data corresponding to that question;

aggregate the scores; and

assign a trust level to the second user based on the aggregated score, wherein the computing device is configured to score, aggregate, and assign a trust level during generation of the trust assessment result data.

4. The system as set forth in claim 1, wherein the computing device is configured to generate at least one trust assessment question upon receipt of the request to establish a relationship between the target user and the second user.

5. The system as set forth in claim 1, wherein the computing device is further configured to:

access a plurality of stored trust assessment questions;

select at least some of the plurality of trust assessment questions; and

present the selected questions to the second user where the computing device accesses, selects, and presents the selected questions during interrogation.

6. The system as set forth in claim 5, wherein the second user is classified based at least in part on determining a relationship between the second user and the target user where determining the relationship includes accessing data defining a social network including the second user and the target user.

7. The system as set forth in claim 6, wherein the computing device is further configured to classify where at least some of the plurality of questions are selected based on the classification of the second user.

8. The system as set forth in claim 6, wherein the second user is classified based at least in part on data identifying at least one prior trust assessment session including the second user.

9. The system as set forth in claim 1, wherein the computing device is further configured to:

send at least one message to the target user after the interrogation of the second user has commenced; and

modify the target user'"'"'s trust level of the second user based on data received from the target user in response to the at least one message.

10. The system as set forth in claim 1, wherein the request includes at least one result address and one or more exit criteria and the computing device is further configured to:

determine whether the exit criteria are satisfied during generation of the trust assessment result data; and

send data including the trust assessment result data to the at least one result address, wherein the exit criteria include an exit trust level and the exit criteria are satisfied once the computed trust level meets or exceeds the exit trust level.

11. The system as set forth in claim 1, wherein the computing device is associated with a peer-to-peer network.

12. The system as set forth in claim 1, wherein the target user and the second user have a pre-existing relationship and the computing device is further configured to:

establish the relationship between the target user and the second user based on the pre-existing relationship.

13. A computing device comprising:

a first storage medium;

a second storage medium, wherein each storage medium includes a plurality of data items associated with a target user and each data item of the plurality of data items is associated with a trust level; and

a processor configured to access the first and second storage mediums and execute instructions directing the computing device to perform actions including;

determine a target user and a second user;

determine a relationship between the target user and the second user;

access a plurality of data items associated with the target user based on the relationship between the target user and the second user, wherein the accessed data items are selected from either the first knowledge base or the second knowledge base according to the relationship where each data item of the plurality of data items are associated with a trust level;

interrogate the second user using the accessed data items where the interrogation is based on the relationship between the target user and the second user;

receive response data from the second user;

determine the extent to which the second user'"'"'s response data matches at least one data item; and

assign a trust level to the second user based on the trust level associated with the at least one matched data item and the interrogating results.

14. The computing device as set forth in claim 13, wherein the computing device is further configured to:

access a plurality of stored trust assessment questions;

select at least some of the plurality of trust assessment questions; and

present the selected questions to the second user where the computing device accesses, selects, and presents the selected questions during interrogation.
