Revocable biometric-based keys for digital signing are provided by, in part, generating a revocable public key at a secure device and transmitting the public key to a registration system for registration to facilitate linking the public key to the secure device user's identity for use in accessing a protected resource. Generating the revocable public key may include generating a salt, storing the salt on the secure device, and temporarily obtaining, by the secure device, biometric data of the user of the secure device. The biometric data is obtained from user biometrics, and the temporarily obtaining is absent storing the biometric data in persistent storage. A public and private key pair is generated at the secure device based, at least in part, on the stored salt and the user's temporarily obtained biometric data.

Embodiments herein provide geolocation notifications to increase collaboration between users. Specifically, a collaboration tool is configured to receive, from a social media application, an indication of a geolocation of a first user, as well as information about an availability of the first user and an availability of a second user. These are used to generate a collaborative meeting event for the first user and the second user according to the geolocation of the first user, the availability of the first user, and an availability of the second user. The second user is presented with content based on a next-best-action (NBA) model from which the second user selects content to present to the first user, which is then configured for the first user. As such, the collaboration tool unifies user geolocation and availability information in order to connect interested users with one another in a mutually beneficial way.

A second user is notified about the geolocation of the first user and the availability of the first user, which is used to generate a collaborative meeting event for the first user and the second user according to the geolocation of the first user, the availability of the first user, an availability of the second user, and a location of the second user. The second user is automatically notified about the collaborative meeting event, which may be automatically scheduled in a calendar application. As such, the collaboration tool unifies user geolocation and availability information in order to connect interested users with one another in a mutually beneficial way.
