Title: Innovations of Shinichiro Harano
Introduction
Shinichiro Harano is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of technology, particularly in the areas of elliptic curve cryptography and digital watermarking. With a total of 3 patents to his name, Harano continues to push the boundaries of innovation.
Latest Patents
One of Harano's latest patents is the "Elliptic Scalar Multiplication System." This invention involves a scalar multiplication method where a point on an elliptic curve is randomized. Despite the randomization, the computational cost remains equivalent to that of non-randomized methods. The operation is performed on both randomized and non-randomized points to derive a scalar-multiplied point from a scalar value and a point on the elliptic curve. The result is randomized while maintaining the computational efficiency.
Another significant patent is the "Digital Watermark Data Embedding Method and Digital Watermark Data Embeddability Analyzing Method." This innovation aims to reduce the processing load associated with embedding digital watermarks in content data. It involves a preliminary process, known as the embedding strength map generating process, which is executed by a preprocessing section. This process runs independently each time new content data is stored in the database. The main process, which is the digital watermark embedding process, is activated when a content delivery request is received from a client terminal.
