One example method for integrating software application content into video conferences includes receiving, by a video conferencing application executed by a client device from a video conference provider, one or more participant video streams, each participant video stream corresponding to a participant in a video conference; receiving, by the video conferencing application from a software application, software application content; receiving, by the video conferencing application from the software application, display layout information; generating, by the video conferencing application, a graphical representation of the video conference according to the display layout information, the graphical representation comprising at least a portion of the software application content and at least one of the one or more participant video streams; and displaying, by the video conferencing application, the graphical representation of the video conference.

Integrating software application content into video conferences

One disclosed example involves a client device joining a videoconferencing meeting in which there is end-to-end encryption, where the end-to-end encryption is implemented by the client devices participating in the meting using a meeting key provided by the meeting host. Thereafter, the client device receives a public key of an asymmetric key pair corresponding to the host of the meeting, where the public key is different from the meeting key. The client device then generates a security code based on the public key and output the security code on a display device. The security code can be compared to another security code generated by another client device participating in the meeting to verify if the meeting is secure. The client device may also receive encrypted videoconferencing data, decrypt it using the meeting key, and output the decrypted videoconferencing data on the display device.

Securing videoconferencing meetings

One disclosed example method includes a leader client device associated with a leader participant generating a meeting key for a video meeting joined by multiple participants. For each participant, the leader client device obtains a long-term public key and a cryptographic signature associated with the participant. The leader client device verifies the cryptographic signature of the participant based on the long-term public key and the cryptographic signature. If the verification is successful, the leader client device encrypts the meeting key for the participant using a short-term private key generated by the leader client device, a short-term public key of the participant, a meeting identifier, and a user identifier identifying the participant. The leader client device further publishes the encrypted meeting key for the participant on the meeting system. The leader client device encrypts and decrypts meeting data communicated with other participants based on the meeting key.
