Abstract
An electronic mail (email) system allows a user to specify a delete time for automatically deleting an email message. Depending on the implementation, the user may be the sender of the message, the recipient, or the system administrator. The delete time may be specified as a duration of time following receipt of the message or as a specified date and time. In either case when the specified delete time expires, the computer that received and stored the message to memory automatically deletes the message. In this way, control can be exercised to prevent the indefinite retention of email messages that may contain sensitive or other confidential information.
Description
Yaker 13 SPECIFIABLE DELETE TIMES FOR EMAIL MESSAGES
Field of the Invention The present invention relates to computer networks that support the transmission of electronic mail (email) messages between nodes of the network.
Cross-Reference to Related Applications This is a continuation-in-part of co-pending application serial number 08/900.793. tiled on 7/2/97 as attorney docket no. Yaker 7, the teachings of which are incorporated herein by reference.
Description of the Related Art Typical computer networks allow a user (i.e., an email sender) to send an email message to one or more other users (i.e., email recipients), who can then each decide independently if and when to read his or her copy of the email message. After an email message is read by a recipient. the recipient typically has the option of deleting the message or saving the message for future use. In some email systems, although a message has been deleted, it can still be recovered from an I 5 electronic "trash bin" containing such deleted messages. Only when the user explicitly empties the trash will email messages become irretrievable by the user. Some systems allow users to select an option whereby the trash is emptied whenever the user logs out of the email system, but this option is typically disabled by default.
One of the drawbacks to conventional email systems is that, unless the recipient explicitly deletes a message and then, if necessary. explicitly empties the trash, the message will be retained indefinitely in the memory of his or her computer. This can be problematic when email messages contains sensitive or confidential material.
Summary Of The Invention The present invention is directed to an email system that allows a user to instruct the system to automatically delete an email message after a specified time or duration. Depending on the options provided in a particular implementation of such an email system, the user may be the sender of an email message, the recipient. or the system administrator. Again, depending on the implementation, this automatic message deletion may apply only to messages that have been read Yaker 13 2 by the recipient or it may apply to any message whether or not the message has been read by the recipient.
In one embodiment of the invention, the present invention is a method and apparatus for processing email messages by a computer. An email message is received and stored into memory, wherein a user-specified delete time is or has been assigned for the message.
The message is then automatically deleted from the memory after etpiration of the delete time.
Brief Description Of The Drawings Fig. 1 shows a block diagram of an email messaging system, according to one embodiment of the present invention;
Fig. 2 shows a flow diagram of the processing implemented by the system of Fig. 1 related . to the preparation and sending of an email message; and Fig. 3 shows a flow diagram of the processing implemented by the system of Fig. 1 related to the receipt and handling of an email message.
Detailed Description I 5 The present invention addresses a security problem related to email systems. fn particular, an email system of the present invention enables a user to specify a time for deleting an email message. The user may be the sender of the message, a recipient of the message, or the system administrator for the computer network. The delete time may be specified in terms of a particular duration of time, e.g., a number of hours. days. or weeks, after transmission or receipt of the message. Alternatively, the delete time may be specified in terms of a time and date by hour. day.
month, and year. In one embodiment, the sender of the email message has the abiliy to spcci h the delete time when preparing the message. Alternatively or in addition, each recipient can specilv a default delete time for each email message he or she receives or a specific delete time for each different email message as the recipient reads that message. The system administrator may also be able to specify default delete times. including different delete times for different network users.
Typically, default delete times, whether set by recipients or system administrators, would be in terms of a particular duration of time rather than a time and date.
Fig. 1 shows a block diagram of a node 100 of a computer neUvork supporting the preparation and sending of outgoing mail messages to one or more other network users a, wll ,m Yaker 13 3 the receipt and handling of incoming email messages from other network users, according to one embodiment of the present invention. The computer network can be any suitable ype of computer network, such as a local area network or intranet or a wide area network or Internet. Similar, node 100 can be any suitable type of computer such as a desktop personal computer or a workstation.
The basic block diagram ~f Fig. 1 show s the general functionality supported by a node of an email system.
In particular, transmitter 104 of Fig. 1 transmits outgoing email messages from node 100.
receiver 106 receives incoming email messages, and memory 108 stores incoming email messages.
Processor 102 coordinates the activities of the other components of node 100, including the preparation and transmission of outgoing email messages as well as the receipt, storage, reading.
and deleting of incoming email messages. Depending on the implementation, an email system can be designed to provide some or all of the following options to network users:
o A sender of an email message can select a delete time (e.g., via either a speciFed date and time or a specified dwation) for each outgoing message.
I S o The sender can set a default delete time in terms of a specified duration for each of his ur her email messages. In addition, the sender can vary the delete time from message to message.
o The sender can vary the delete time from recipient to recipient for a single email message o The sender has the option of specifying that the message be deleted only after the mcssa~~e has been read by the recipient or whether or not the message has been read.
o The sender has the option of specifying that the message be deleted as soon as it is read by a recipient, whether or not the specified delete time has expired.
o The recipient or system administrator can set a default delete time (e.g., t~picallv a specified duration) for all incoming messages.
o The recipient has the opUOn of specifying that the message be deleted either (al only at~nr the message has been read by the recipient or (b) whether or not the message has been read.
o The recipient can set a specific delete time as each incoming message is read by the recipient.
Yaker 13 4 o The recipient can override a delete time specified by the sender.
In any event, assuming that the relevant conditions are met, after the expiration of a specified delete time, processor 102 of Fig. 1 will automatically delete the corresponding email message, where "delete" may mean "make the message unavailable to the recipient," in which case, it is equivalent to sending an email message to a trash bin and then emptying the trash for conventional email systems. Depending on the implementation. the term "delete" as understood for the present invention may also imply an operation that completely erases the corresponding region of memory 108, so that even system administrators using special memory reconstruction routines cannot recover the message.
Fig. 2 shows a flow diagram of the processing implemented by node 100 of Fig.
