技術說明

一種基於壓縮信號的身分識別系統及其方法，透過當感測端處於識別模式時，持續量測使用者在至少一第一預定時間長度內的生理識別信號，對在至少一第一預定時間長度內的生理識別信號進行壓縮程序以生成第一壓縮信號，傳送第一壓縮信號；識別端接收第一壓縮信號，根據主要特徵向量取得第一壓縮信號在鑑別子空間的第一鑑別資訊，並根據來自學習端的分類模型對第一鑑別資訊進行識別，以判斷該使用者為多個受測者之一。因此，感測端因壓縮技術減少傳送信號的能量，識別端不需重建感測端所傳送的第一壓縮信號即可進行使用者的身分識別。 【英文】 An identity recognition system based on compressed signal and a method thereof are provided. When a sensing end is in a recognition mode, a physiological identification signal of the user for at least one first predetermined length of time is continuously measured, and a compression process is performed on the physiological identification signal for the at least one first predetermined length of time to generate a first compressed signal, and the first compressed signal is transmitted. A recognition end receives the first compressed signal, obtains a first identification signal of the first compressed signal in a discrimination subspace according to a principal eigenvector, and identify the first identification signal according to a classification model from a learning end to determine that the user is one of multiple subjects. Therefore, the sensing end reduces the energy of the transmitted signal by the compressive technology, and the recognition end does not need to reconstruct the first compressed signal transmitted by the sensing end to performs identification on the user's identity.
