Description

Metal safety paper capable of identifying and preventing theft

Technical Field

The utility model relates to a theftproof safety paper field, in particular to metal security paper of distinguishable and theftproof.

Background

Today, information is presented and spread in an electronic mode mostly when information carriers are diversified, but confidential government documents, files and the like are still circulated by paper carriers because the paper carriers have the foundation and reliability. Compared with carriers such as compact discs, U discs, mobile hard disks, hard disks and the like, paper carriers are thin in thickness and incapable of encrypting file contents, and effective and economic technical means for controlling the paper carriers are not available all the time.

The security paper is also called security paper, safety paper or security paper, and is a product for preventing the leakage of the security of the scene security documents of security units, scientific research units, troops, chip companies and the like. In the prior art, amorphous bare fibers with a large Barkhausen effect are implanted into paper, the paper is named as electromagnetic induction security paper, and the electromagnetic induction security paper needs to be matched with an electromagnetic wave anti-theft system with the frequency of 1-20K for use. When the confidential paper is artificially taken away from the confidential area, the electromagnetic induction security paper can trigger a specific device to alarm, so that the confidential document is effectively prevented from being intentionally or unintentionally taken away from the confidential area by personnel. The whole piece of confidential paper is taken out to trigger specific equipment to alarm, and even if the confidential paper is maliciously damaged and shredded and is partially taken out, the confidential paper also can trigger the specific equipment to alarm. The security paper is not different from ordinary paper, and can be written or printed as ordinary paper. The security paper has various types, such as security printing paper, security writing paper, security engineering paper, security drawings and the like, and can meet the requirements of different working departments.

However, the electromagnetic wave low-frequency signals with the frequency of 1-20K commonly used by the electromagnetic induction security paper are easily interfered by high-power equipment such as peripheral metal inductors, gates, metal shielding walls and the like to generate false alarm or false alarm.

In addition, during printing and writing, ink can penetrate into the RFID tag, affect normal use of the RFID chip in the RFID tag, and even damage the RFID chip.

Therefore, there is a need in the art to develop a security paper with high detection sensitivity and accuracy, low preparation cost, reduced occurrence of false alarm or failure, and effectively avoiding damage to the RFID chip during printing and handwriting.

The RFID induction antenna is made of cobalt. In other embodiments, the material of the RFID inductive antenna may be at least one of cobalt, nickel, aluminum, iron, tin, chromium, and manganese.

Several RFID tags 4 are distributed at different locations of the security paper (not shown).

In this embodiment, the waterproof layer 3 is a polyethylene layer disposed between the upper paper sheet 1 and the lower paper sheet 2, and the waterproof layer 3 may also be a polypropylene layer, or an overlapping layer of a polyethylene layer and a polypropylene layer. The waterproof layer 3 can effectively prevent ink from permeating into the RFID tag 4 in the printing, copying or handwriting processes, so that the use of the RFID chip is influenced, and even the RFID chip is damaged.

In this embodiment, the waterproof layer 3 has the same size as the upper and

lower sheets

1 and 2.

In consideration of the fact that, when actually printing or writing, in order to make the typesetting of characters neat and beautiful, the paper is usually left blank, that is, a reasonable margin is set, and no printing or writing operation is performed in the margin area. Thus, in one embodiment, the upper paper 1 or the lower paper 2 may be provided with writing regions, respectively, and the writing regions and the non-writing regions may be marked with dividing lines. It will be appreciated that the dividing line may be provided by light ink printing, or by a dotted line cutting, which may also be referred to as a tear line, i.e. by a dotted line cutting hob or a dotted line knife. In order to improve the utilization efficiency of materials and avoid waste, the size of the waterproof layer 3 is the same as that of the writing area.

In addition, the arrangement of the writing area can also cause confusion to thieves, and the anti-theft, privacy keeping and capturing effects are improved. For example, a thief may misunderstand that the non-writing area does not include the theft-proof metal material, thereby tearing out fragments of the non-writing area, recording secret information thereon, and then taking out. As the anti-theft metal material still exists in the non-writing area, the chip of the security paper (non-writing area) carried by a thief can be detected during security detection, and the thief is stolen and obtained.

In this embodiment, the anti-theft metal material is iron. In other embodiments, the theft-proof metal material may also be at least one of iron, aluminum, copper, zinc, titanium, magnesium, zirconium, hafnium, niobium, and tantalum.

Shielding layer 5 can also be set up around RFID label 4, further avoid theftproof metal material to RFID label 4's signal influence.

Wherein, the shielding layer 5 comprises an electromagnetic shielding material iron oxide.

The shielding layers 5 disposed on the upper surface and the lower surface of the RFID tag 4 cover the entire area of the RFID tag 4, and may cover a part of the area of the RFID tag 4. When the shielding layer 5 covers the whole area of the RFID label 4, the shielding effect is more ideal, and the signal sent by the RFID label 4 is more favorably received by an RFID label detection device.

Wherein, the shielding layer 5 is embedded in the waterproof layer 3.

When the anti-theft metal safety paper detection device is used, the metal safety paper and the safety paper detection device are used in a combined mode, the safety paper detection device comprises an RFID detection system and a metal detection system, the RFID label detection system is used for obtaining identification information and anti-theft information in an RFID label, the metal detection system is used for detecting anti-theft metal materials in the upper surface paper 1 and the lower surface paper 2, double anti-theft is achieved, and detection sensitivity and accuracy are improved.

Shielding layers 5 can be arranged around the RFID anti-theft area 7, so that the signal influence of anti-theft metal materials on the RFID tag 4 is avoided. It is understood that since the RFID theft prevention area 7 is not provided with the theft prevention metal material, metal theft prevention cannot be achieved, and if a thief tears out the upper paper 1 or the lower paper 2 here, there may be a risk of disclosure. Therefore, the RFID theft prevention areas 7 of the upper and

lower sheets

1 and 2 can be bonded to the waterproof layer 3 by the strong adhesive layer 8 to prevent the RFID theft prevention areas from being torn off by a thief.
