A method, system and computer program product for sharing resources among remote repositories. In a shared file system, a resource identifier and metadata are created for a resource, where the resource identifier is stored in a lock file in a shared volume accessible by the remote repositories. The lock file is then released in response to distributing the associated resource to the remote repositories. Alternatively, in a peer-to-peer system, a request is received to create, read, update or delete a resource stored in a content repository. A resource name, a resource version and/or a resource fingerprint are received in connection with the request to create, read, update or delete the resource in the content repository. A determination is then made as to whether the received resource name, resource version and/or resource fingerprint matches the respective resource name, resource version and/or resource fingerprint stored in a node graph for the resource.

Embodiments of the invention address deficiencies of the art in respect to electronic messaging security through replicated certificate stores and provide a method, system and computer program product user-specific certificate repository replication. In one embodiment of the invention, a method of replicating with multiple different messaging systems disposed in correspondingly different computing clients, retrieving a local repository of untrusted certificates from each of the different messaging systems during replication, and associating each retrieved local repository with a particular end user can be provided. Moreover, the method can include updating a global repository of untrusted certificates with the untrusted certificates of each local repository while eliminating redundant instances of an untrusted certificate present in different retrieved local repositories.

The present invention provides a method, system, and computer program product for transparent on-demand certificate provisioning for secure email. The method comprises: generating a keypair and a self-signed certificate; requesting a certificate from a certification authority; temporarily securing email using the self-signed certificate; and securing email using the requested certificate, after receipt of the requested certificate from the certification authority. The present inventions uses self-signed certificates as an initial, interim security mechanism, provides automatic submission of certificate requests and renewal requests, provides an administrative policy to specify when keypairs and self-signed certificates are generated by a user's client system, and when certificate requests are submitted, and provides automatic transition from end-user defined trust to delegated trust based upon CA-issued certificates.

Transparent on-demand certificate provisioning for secure email

A system and method for providing notification of significant events such as received or disposed of messages in a unified communication services network. Notifications are event based and may be filtered according to predetermined criteria. One or more event managers may, among other things, manage the receipt and dispersal of event notifications and pass the notifications to one or more notification handlers for dispersal of the notifications to subscribers.

Notification services within a unified communications service

A system and method for enabling annotation of audible voice messages in a unified communication services (UCS) system. In some embodiments, subscribers access a message presentation form that enables simultaneous playback and annotation of audible voice messages.
