Abstract

Based on information used by the external system to identify a target user, the external system generates a target user hash identifier that is communicated to the social networking system along with a message. Using information from user profiles maintained by the social networking system, the social networking system generates hash identifiers for its users and compares the target user hash identifier to the generated hash identifiers hash identifiers for social networking system users are generated. The social networking system sends the message to a user associated with a hash identifier generated from user profile information that matches the target user hash identifier. Hence, an external application may communicate with social networking system users without accessing access information about the users maintained by the social networking system.

First claim

What is claimed is:

1. A method comprising:
receiving, from an application external to a social networking system, a request to generate a message for delivery to one or more target users via the social network system, wherein the one or more target users are users of the application, the request including a message content for the generated message and an identifier hash for each of the one or more target users generated by the application from an item of personally identifiable information associated with a target user using a specified hash generation function, wherein the application does not send the item of personally identifiable information;
accessing one or more user profiles maintained by the social networking system, a user profile including information about social networking system users;
generating, an identifier hash for each of the one or more social networking system users by applying the specified hash generation function to personally identifiable information in the user profile about the social networking system user;
for each of the received identifier hashes for the one or more target users, determining if the generated identifier hash matches the received identifier hash for the target user in the received request from the application external to the social networking system; and
responsive to determining the match:
generating a message, by the social networking system, to provide to one or more users of the social networking system associated with the one or more matched identifier hashes wherein the generated message includes the message content from the application external to the social networking system, and
providing, by the social networking system, the generated message to one or more users of the social networking system associated with the one or more matched identifier hashes.

2. The method of claim 1 , wherein the identifier hash for a target user is a one-way function on the item of personally identifiable information of the target user.

3. The method of claim 1 , wherein the identifier hash for a target user is a cryptographic hash on the item of personally identifiable information of the target user.

4. The method of claim 1 , wherein the item of personally identifiable information of the target user is selected from the group consisting of: a social networking system identifier, a name, an email address, a phone number, a subscriber identity module (SIM) card identifier, a media access control (MAC) address, a credit card number, a social security number, and any combination thereof.

5. The method of claim 1 , wherein the information in the user profiles is selected from the group consisting of: a social networking system identifier, a name, an email address, a phone number, a subscriber identity module (SIM) card identifier, a media access control (MAC) address, a credit card number, a social security number, and any combination thereof.

6. The method of claim 1 , wherein providing the generated message to the selected users of the social networking system associated with the selected identifier hashes for the one or more social networking system users comprises:
transmitting the generated message directly to the one or more selected users of the social networking system associated with the selected identifier hashes for the one or more social networking system users.

7. The method of claim 1 , wherein the generated message identifies the application generating the message.

8. The method of claim 1 , wherein providing the generated message generated by the application to selected users of the social networking system associated with the selected identifier hashes for the one or more social networking system users comprises:
posting the generated message to a page in the social networking system associated with the application, the generated message visible to users of the social networking system associated with the selected identifier hashes viewing the page and not visible to users of the social networking system not associated with the selected identifier hashes viewing the page.

9. The method of claim 1 , wherein the generated message is a social networking object associated with one or more social networking users.

10. A method comprising:
receiving, from a system external to a social networking system, a request to generate a message for delivery to one or more target users via the social network system, wherein the one or more target users are users of the application, the request including a message content for the generated message and an identifier hash for each of the one or more target users generated by the system external to the social networking system from an item of personally identifiable information associated with a target user using a specified hash generation function, wherein the system does not send the item of personally identifiable information;
accessing one or more user profiles maintained by the social networking system, a user profile including information about social networking system users;
generating an identifier hash for each of the one or more target users by applying the specified hash generation function to personally identifiable information in the user profile about the social networking system user;
for each of the received identifier hashes for the one or more target users, determining if the generated identifier hash matches the received identifier hash for the target user in the received request from the system external to the social networking system; and
responsive to determining the match:
generating a message, by the social networking system, to provide to one or more users of the social networking system associated with the one or more matched identifier hashes wherein the generated message includes the message content from the application external to the social networking system, and
providing, by the social networking system, the generated message to one or more users of the social networking system associated with the one or more matched identifier hashes.

11. The method of claim 10 , wherein the identifier hash for a target user is a one-way function on the item of personally identifiable information of the target user.

12. The method of claim 10 , wherein the identifier hash for a target user is a cryptographic hash on the item of personally identifiable information of the target user.

13. The method of claim 10 , wherein the item of personally identifiable information of the target user is selected from the group consisting of: a social networking system identifier, a name, an email address, a phone number, a subscriber identity module (SIM) card identifier, a media access control (MAC) address, a credit card number, a social security number, and any combination thereof.

14. The method of claim 10 , wherein the information in the user profiles is selected from the group consisting of: a social networking system identifier, a name, an email address, a phone number, a subscriber identity module (SIM) card identifier, a media access control (MAC) address, a credit card number, a social security number, and any combination thereof.

15. The method of claim 10 , wherein providing the generated message to selected users of the social networking system associated with the selected identifier hashes for the one or more social networking system users comprises:
transmitting the generated message directly to the selected users of the social networking system associated with the selected identifier hashes for the one or more social networking system users.

16. The method of claim 15 , wherein the generat
