Abstract
The invention relates to an encoding scheme which utilizes the feature that X rays emitted or absorbed by elements are unique and thus the X rays can be utilized as element fingerprints. Height of X ray absorption spectrum of two or more than two kinds of different elements, area of the absorption spectrum and various combination processing information of the height of the X ray absorption spectrum and the area of the absorption spectrum are utilized to serve as basic encoding information, and the encoding scheme is formed. By utilizing a plurality of different elements, the encoding scheme has the advantages of invisibility, large number of encoding bits and large encoding capacity; and meanwhile, the encoding scheme has the functions of anti-counterfeit and genuine piece authentication.
Description
Technical field
The present invention relates to a kind of X ray absorption spectra information of element of utilizing as the encoding scheme of coded message, and the detection technique of this encoding scheme.This encoding scheme has more than stealth, coding figure place and the large feature of code capacity.Utilize this encoding scheme and detection method can identify article or commodity, can carry out the true and false authentication of commodity simultaneously.
Background technology
At present popular encoding scheme is to utilize the Quick Response Code recognition methods of method or the figure etc. such as bar code of numeral, letter marshalling, is similar in addition the segmentation Digital ID method as internet-ip address etc.These methods can reach identification function by well-regulated deciphering translation by specific coding method, and have function of keeping secret.The encoding scheme the present invention relates to is recessive, must just can obtain corresponding coded message by the analysis of corresponding method of detection, has feature hidden, that encrypt.
Summary of the invention
Encoding scheme involved in the present invention is to utilize the X ray of element transmitting or absorption to have uniqueness, can be used as the feature that elemental fingerprints uses, utilize height, the area of absorption spectrum and the various combined treatment information of absorption spectrum height and absorption spectrum area of the X ray absorption spectrum of two or more different element as basic coding information, form encoding scheme.Utilize multiple different element, this encoding scheme has more than stealth, coding figure place and the large feature of code capacity, and this encoding scheme has false proof and genuine piece authentication function simultaneously.
