Abstract

Methods and systems are disclosed herein for a message archiving system that may first be enabled for a particular group. Once enabled, the message archiving system may start archiving the messages received by the members of the group so that those messages may be reviewed for various purposes. To enable archiving, the message archiving system may, upon receiving a command to enable archiving, initiate a group update. The group update may generate a binary tree for the group on the archiving device. The binary tree enables the archiving device to receive and decrypt messages received by the group. The message archiving system may then resolve a public and private key for encrypting and decrypting messages once they have been designated for archiving.

Claims20

Dependent claims

A system for providing message archiving for groups, the system comprising:

one or more processors;
and
a non-transitory, computer-readable storage medium storing instructions, which, when executed by the one or more processors, cause the one or more processors to:
receive, at an archiving device from an administrator device associated with a group administrator, an archiving request to enable archiving for a group, wherein the group is associated with a binary tree, and wherein the binary tree comprises a plurality of leaf nodes, with each leaf node of the plurality of leaf nodes representing a corresponding user within the group;
initiate a group update to add the archiving device to the group as a member of the group, wherein the archiving device is added to the binary tree as a new leaf node;
transmit a command to the administrator device to resolve an archiver private key for decrypting archived messages associated with the group and an archiver public key for encrypting the archived messages associated with the group;
receive, in response to the command, the archiver private key and the archiver public key;
cause the archiver private key to be stored in a key vault in association with a group identifier associated with the group;
and
publish the archiver public key in association with the group identifier, wherein the group identifier is used to retrieve the archiver public key for encrypting received messages.

7 more elements

A method for archiving group messages, the method comprising:

receiving an archiving request to enable archiving for a group, wherein the group is associated with a binary tree, and wherein the binary tree comprises a plurality of leaf nodes, with each leaf node of the plurality of leaf nodes representing a corresponding user within the group;
initiating a group update to add an archiver to the group as a member of the group, wherein the archiver is added to the binary tree as a new leaf node;
resolving an archiver private key for decrypting archived messages associated with the group and an archiver public key for encrypting the archived messages associated with the group;
in response to the command, receiving the archiver public key, wherein the archiver private key is stored in association with a group identifier corresponding to the group;
and
publishing the archiver public key to be used with the group identifier.

3 more elements

One or more non-transitory, computer-readable storage media storing instructions thereon, which, when executed by one or more processors, cause the one or more processors to perform operations comprising:

receiving an archiving request to enable archiving for a group, wherein the group is associated with a binary tree, and wherein the binary tree comprises a plurality of leaf nodes, with each leaf node of the plurality of leaf nodes representing a corresponding user within the group;
initiating a group update to add an archiver to the group as a member of the group, wherein the archiver is added to the binary tree as a new leaf node;
resolving an archiver private key for decrypting archived messages associated with the group and an archiver public key for encrypting the archived messages associated with the group;
receiving, in response to the command, the archiver private key and the archiver public key;
causing the archiver private key to be stored in association with a group identifier corresponding to the group;
and
publishing the archiver public key to be used with the group identifier.
