Mutual privacy management
View Patent ↗Determining whether a message should be allowed to be sent is determined. A request to send a message to a recipient is received from a sender's client device. A determination is made at a server as to whether the sender is allowed to send the message to the recipient, based on a privacy list. A response to the sender is sent, based on the determination.
1. A system, comprising:
a processor configured to:
receive, at a server, a sender's privacy list from a sender's client device;
receive, at the server, the recipient's privacy list from a recipient's client device, wherein the sender's client device is different from the recipient's client device;
receive, at the server, a request, from the sender's client device, for user information for an intended recipient of a message, wherein the request includes a first hashed representation of a recipient's username and a second hashed representation of a sender's username;
determine, at the server, whether the sender is permitted to send the message to the recipient based at least in part on a sender's privacy list stored at the server, wherein the determining includes comparing the first hashed representation to entries included in the sender's privacy list;
determine, at the server, whether the recipient is permitted to receive the message from the sender based at least in part on a recipient's privacy list stored at the server, wherein determining includes comparing the second hashed representation to entries included in the recipient's privacy list;
in response to a determination that the sender appears on the recipient's privacy list, deny the request for user information received from the sender's client device; and
a memory coupled to the processor and configured to provide the processor with instructions.
2. The system of claim 1 wherein receiving the request includes receiving a request for a public key of the recipient.
3. The system of claim 1 wherein the sender's privacy list is editable by the sender.
4. The system of claim 1 wherein the recipient's privacy list is editable by the recipient.
5. The system of claim 1 wherein the recipient's privacy list comprises a block list.
6. The system of claim 1 wherein the sender's privacy list comprises an allowed list.
7. The system of claim 1 wherein determining that the sender is not allowed to send the message includes determining whether the sender has configured the sender's privacy list as a block list.
8. The system of claim 1 wherein determining that the sender is not allowed to send the message includes determining whether the sender has configured the sender's privacy list as an allow list.
9. The system of claim 1 wherein the processor is further configured to:
provide, from the server, a notification to the sender's client device indicating that the sender is not permitted to transmit the message to the recipient.
10. The system of claim 1 wherein the sender's privacy list is editable by an administrator associated with the sender and is not editable by the sender.
11. The system of claim 1 wherein the recipient's privacy list is editable by an administrator associated with the recipient and is not editable by the recipient.
12. A method, comprising:
receiving, at a server, a sender's privacy list from a sender's client device;
receiving, at the server, the recipient's privacy list from a recipient's client device, wherein the sender's client device is different from the recipient's client device;
receiving, at the server, a request, from the sender's client device, for user information for an intended recipient of a message, wherein the request includes a first hashed representation of a recipient's username and a second hashed representation of a sender's username;
determining, at the server, whether the sender is permitted to send the message to the recipient based at least in part on a sender's privacy list stored at the server, wherein the determining includes comparing the first hashed representation to entries included in the sender's privacy list stored at the server;
determining, at the server, whether the recipient is permitted to receive the message from the sender based at least in part on a recipient's privacy list stored at the server, wherein the determining includes comparing the second hashed representation to entries included in the recipient's privacy list; and
in response to a determination that the sender is on the recipient's privacy list, denying the request for user information received from the sender's client device.
13. The method of claim 12 wherein receiving the request includes receiving a request for a public key of the recipient.
14. The method of claim 12 wherein the sender's privacy list is editable by the sender.
15. The method of claim 12 wherein the recipient's privacy list is editable by the recipient.
16. The method of claim 12 wherein the recipient's privacy list comprises a block list.
17. The method of claim 12 wherein the sender's privacy list comprises an allowed list.
18. The method of claim 12 wherein determining that the sender is not allowed to send the message includes determining whether the sender has configured the sender's privacy list as a block list.
19. A computer program product embodied in a non-transitory, tangible computer readable storage medium and comprising computer instructions for:
receiving, at a server, a sender's privacy list from a sender's client device;
receiving, at the server, the recipient's privacy list from a recipient's client device, wherein the sender's client device is different from the recipient's client device;
receiving, at the server, a request, from the sender's client device, for user information for an intended recipient of a message, wherein the request includes a first hashed representation of a recipient's username and a second hashed representation of a sender's username;
determining, at the server, whether the sender is permitted to send the message to the recipient based at least in part on a sender's privacy list stored at the server, wherein the determining includes comparing the first hashed representation to entries included in the sender's privacy list stored at the server;
determining, at the server, whether the recipient is permitted to receive the message from the sender based at least in part on a recipient's privacy list stored at the server, wherein the determining includes comparing the second hashed representation to entries included in the recipient's privacy list; and
in response to a determination that the sender is on the recipient's privacy list, denying the request for user information received from the sender's client device.
