Abstract

A server includes volatile and non-volatile memories for storing messages received from a client device. A message reception module of the server stores a message received from a first client device in the volatile memory for an extended time period based on an indicator included in the message. The message reception module deletes the message from the volatile memory based on detection of a triggering event or stores the message in the non-volatile memory based on not detecting the triggering event before the extended time period has expired. The triggering event may include the message having been read by all specified recipients of the message. The indicator may be included in the message based on a relationship of the message to other messages. The message including the indicator may be related to other messages as part of a same conversation that has been determined to be suitable for short-term storage.

Claims

1. A system comprising:

hardware processing circuitry configured to perform operations comprising;

determine that a message is part of a conversation that includes a previous message that was stored for less than a specified time period;

store the message in a volatile memory based on the determination; and

copy the message from the volatile memory to a non-volatile memory based on not detecting a specified triggering event prior to a storage time of the message in the volatile memory exceeding the specified time period.

2. The system of claim 1, the operations further comprising deleting the message from the volatile memory based on detecting the triggering event prior to a storage time of the message in the volatile memory exceeding the specified time period.

3. The system of claim 1, wherein the triggering event comprises the message having been read by all specified recipients of the message.

4. The system of claim 1, the operations further comprising receiving the message from a communication device.

5. The system of claim 4, wherein the message is stored in the volatile memory based on:

a mode of operation of the communication device;

a count of messages in the conversation;

a size of the message;

a recipient of the message;

or a subject of the message.

6. The system of claim 4, wherein a mode of operation of the communication device comprises a chatroom mode of operation, the triggering event comprises exiting the chatroom mode transmitting a warning to the communication device that the message will be automatically deleted upon exiting chatroom mode.

7. The system of claim 1, the operations further comprising

transmitting the message to a second communication device associated with a recipient of the message upon receipt of a request from said second communication device;

inserting instructions into the message to instruct the second communication device to display the message for only a predetermined time period; and

deleting the message from at least one of the volatile memory and the non-volatile memory based on the specified time period expiring.

8. The system of claim 7, wherein the triggering event comprises responding to the message at the second communication device.

9. A method comprising:

determining that a message is part of a conversation that includes a previous message that was stored for less than a specified time period;

storing the message in a volatile memory based on the determination; and

copying the message from the volatile memory to a non-volatile memory based on not detecting a specified triggering event prior to a storage time of the message in the volatile memory exceeding the specified time period.

10. The method of claim 9, further comprising deleting the message from the volatile memory based on detecting the triggering event prior to a storage time of the message in the volatile memory exceeding the specified time period.

11. The method of claim 9, wherein the triggering event comprises the message having been read by all specified recipients of the message.

12. The method of claim 9, further comprising receiving the message from a communication device.

13. The method of claim 12, wherein the message is stored in the volatile memory based on:

a mode of operation of the communication device;

a count of messages in the conversation;

a size of the message;

a recipient of the message;

or a subject of the message.

14. The method of claim 13, wherein the mode of operation of the communication device comprises a chatroom mode of operation, the triggering event comprises exiting the chatroom mode transmitting a warning to the communication device that the message will be automatically deleted upon exiting chatroom mode.

15. The method of claim 9, further comprising

transmitting the message to a second communication device associated with a recipient of the message upon receipt of a request from said second communication device;

inserting instructions into the message to instruct the second communication device to display the message for only a predetermined time period; and

deleting the message from at least one of the volatile memory and the non-volatile memory based on the specified time period expiring.

16. The method of claim 15, wherein the triggering event comprises responding to the message at the second communication device.

17. A non-transitory computer readable medium comprising instructions that when executed configure hardware processing circuitry to perform operations comprising:

determining that a message is part of a conversation that includes a previous message that was stored for less than a specified time period;

storing the message in a volatile memory based on the determination; and

copying the message from the volatile memory to a non-volatile memory based on not detecting a specified triggering event prior to a storage time of the message in the volatile memory exceeding the specified time period.

18. The non-transitory computer readable medium of claim 17, the operations further comprising receiving the message from a communication device.

19. The non-transitory computer readable medium of claim 18, wherein the message is stored in the volatile memory based on:

a mode of operation of the communication device;

a count of messages in the conversation;

a size of the message;

a recipient of the message;

or a subject of the message.

20. The non-transitory computer readable medium of claim 19, wherein the mode of operation of the communication device comprises a chatroom mode of operation, the triggering event comprises exiting the chatroom mode transmitting a warning to the communication device that the message will be automatically deleted upon exiting chatroom mode.
