The invention provides a DNA chip based cipher system. The DNA of the DNA chip of the cipher system is a random sequence G (i, j). Oligonucleotide probes S (i, j) are oligonucleotide fragments obtained through artificially synthesizing the reverse complement sequences of a small-segment DNA sequence randomly intercepted from the random DNA sequence G (i, j) corresponding to the lattices of the DNA chip, and the uniqueness of the small-segment DNA sequence in the DNA chip is determined through using BLAST. Information encryption is that a DNA chip lattice distribution map M is marked with different G (i, j) to represent plaintext information, and then the oligonucleotide probes S (i, j) corresponding to the G (i, j) are mixed; and information decryption is that the oligonucleotide probes S (i, j) are hybridized with the random sequence DNA sequence. The encryption of same plaintext information can be realized through a large amount of different S (i, j) probe mixture combinations and can be admixed with any unlabeled DNA at will. The S (i, j) probes are composed of the random DNA sequence, and plaintext information related information is not coded in the DNA sequences of the mixtures of the S (i, j) probes, so the system cannot be decoded.

The invention discloses a novel absolute type self-synchronizing barcode displacement sensor and a measurement method thereof. The novel absolute type self-synchronizing barcode displacement sensor comprises a ruler belt with a particular one-dimensional barcode, and a reading box with a reading unit positioned towards the particular one-dimensional barcode. The reading box and the ruler belt move relative to each other, so that the information of an absolute position is measured through the code reading of the absolute position information. A code reading sensor expresses a code containing the absolute position information in the form of a particular one-dimensional barcode based on the intelligent image processing technology and the stripe difference principle. Meanwhile, the particular one-dimensional barcode is read by the reading box, so that the displacement and the absolute position value of an object can be measured accurately. The measuring range of the sensor is almost not limited at all. The ruler belt is a flexible belt and can be installed along a straight-line track or a curve track. No contact friction is generated during the relative movement process, and the reading gap is self-adaptive. The coding length is almost unlimited. Therefore, the sensor can be widely applied to the fields of water conservancy, hydropower, industrial and mining enterprises, traffic and transportation, green and environmental protection, military equipment and the like.
