With a total of 5 patents to her name, Tada continues to push the boundaries of innovation in her field.

Latest Patents

One of her latest patents is a streaming system for distributing encrypted compressed image data. This invention focuses on a streaming system that encrypts compression-encoded image data for distribution via a network using a predetermined transport protocol. The streaming server transmits encrypted stream data to a client terminal based on RTP packet standards. The encryption is performed every encryption block size from the leading portion of each Group of Pictures (GOP), while ensuring that the last data, which is less than the encryption block size, remains unencrypted. Additionally, portions of prior and/or posterior stream data are stored in an extended area of the RTP header, allowing the size of transmitted stream data to be an integral multiple of the encryption block size. This innovative approach helps suppress the increase in size due to encryption, enabling support for both real-time production and download reproduction without the need for encryption replacement.
