Latest Patents

The provided information lists one patent for Shridhar: “Systems and Methods for On-Device Person Recognition and Provision of Intelligent Alerts.” The invention describes a decentralized, multi-camera system in which devices such as security cameras and video doorbells detect and recognize faces locally. The device filters out static or low-quality images, aligns faces, and excludes images with substantial facial occlusion before generating a face embedding and comparing it with locally stored reference embeddings. Matching results are then sent to cloud services, which can help notify the device owner whether the person is known or a stranger. Because face detection and recognition occur on the device, the system is designed to avoid transmitting sensitive facial information to the cloud and to support user privacy.

Career Highlights

The available information identifies Shridhar’s work at Google Inc. and records one patent associated with him. His described invention combines local image processing, facial recognition, and alert delivery in a system intended to balance useful security notifications with privacy protections.

Collaborations

Mohammad Afshar and George Alban Heitz are identified as Shridhar’s coworkers. The provided information does not specify their roles in the patent or the nature of their collaboration.

Conclusion

Saajan Shridhar’s listed patent focuses on performing person recognition directly on connected devices, enabling intelligent alerts while limiting the transfer of sensitive facial data.
