Abstract: An apparatus, system, and method are disclosed for sharing referenced content through collaborative business applications. The method includes detecting referenced content in an electronic communication. The referenced content references content stored in an external repository. The referenced content identifies a registered external repository connector. The method also includes determining that an Access Control List (“ACL”) for the referenced content lacks an entry for a recipient of the electronic communication. The method includes generating an ACL entry for the recipient in response to the recipient lacking an entry in the ACL for the referenced content. The ACL entry controls access to the referenced content for the recipient. The ACL entry is defined based on a security policy associated with the recipient.

Abstract: A computer program product that includes a computer useable storage medium to store a computer readable program for proximity-based authentication for managing personal data that, when executed on a computer, causes the computer to perform operations. The operations include receiving a request for personal data from a data access device, determining a first location corresponding to a location of the data access device, and determining a second location corresponding to a location of an authentication device. The operations also include transmitting the personal data to the data access device if the first location is within a threshold distance of the second location.
