Software development is a promising industry. However, the biggest problem existing in China is piracy. Some of the software, which was a painstaking result of the developers, was well responded at first, but then almost disappeared in one or two months. That was because the pirated discs were dispensing this software. What is even worse, some of the software has been slightly changed and then grabbed a large number of customers, eventually edging the patented software out of the market.

Therefore, we should take encryption measures. It is an inevitable choice of software developers to curb piracy with technological means. However, it is not easy to encrypt software. It requires good encryption algorithms as well as some advanced anti-debug and anti-decryption means. It should be able to cope with various decryption tools and people good at decrypting. In addition, compatibility must be considered in software encryption so that the encrypted software and normal software could be run on various kinds of operating systems and computers.

Software encryption is a very special professional area, which requires rich hardware knowledge as well as an in-depth analysis and research. From the first encryption card we developed under DOS, we have been working in this field for many years. Each update of operating system is both a challenge and an opportunity for us. Many companies in this area have been eliminated due to a failure to catch up with the pace of Windows update. Backed by technical strength of the Chinese Academy of Sciences, we developed relevant products for the operating systems from DOS, Windows3.1to Windows98. Our customers have kept increasing. Many of them have cooperated with us for many years. It is our technological strength and service that help us succeed.

1. Encryption card

Price: Wholesale 220 yuan, retail 270 yuan
Plugged in the expansion slot, it can be used to encrypt executable documents of DOS, Win16 and Win32. Jinque's encryption card bears the following features:

1. High degree of encryption The card can monitor single step interrupt and breakpoint interrupt through hardware so as to recognize and intercept various debug attempts. Through hardware algorithm, the card restores the encrypted software. But the hardware algorithm cannot be tracked. Without the help of encryption card, the encrypted software is only a pile of scrambling codes. So the degree of encryption of the encryption card is much higher than that of Dongles.
2. Good compatibility There has been no problem found with the tens of thousands of sets of encryption cards, from the 286 computers to the Pentium computers.

2. Encryption card for industrial personal computers

Price: Wholesale 230 yuan, retail 280 yuan
In addition to the features described in (1), it also possesses the anti-interference ability, which can help cope with harsh environments.

Dongles (Micro dog)

Price: Wholesale 80 yuan, retail 120 yuan

It is a device of software encryption plugged on the parallel port. It can encrypt the executable documents under DOS, Win16 and Win32. In addition to the functions of normal Micro dog, our products can offer the function of installation. 　　　　

The so-called installation function refers to the special program after the Dongles is plugged. Mover the key is transferred from Dongles into the current machine. After the Dongles is removed, the encrypted software can still (or can only) run on the current computer. As lots of advanced encryption algorithms and lots of anti-encryption technologies are adopted, the encrypted documents cannot be debugged and analyzed, or copied for other computers. This function was developed in answer to the demand of our customers one year ago. At that time, many of them found that new Dongles bits old Dongles, which was not convenient. Customers more and more like this function, which has even become one of the reasons for them to choose our products. With the launches of many new printers, the conflict between Dongles and printers will be hard to avoided. With this installation function, such conflict and inconvenience will be avoided.

Price: DOS/Win16 /Win32: 1400 yuan /1600 yuan /1800 yuan

This is a kind of cheapest way of encryption. So long as you buy a set of encryption software, numerous key disks can be created. It adopts track gap fingerprint reading, which is unduplicated. And it carries 30 sets of random encryption algorithms. The unique characteristics we can offer are:

1. The number of machines and times of installation can be set to ensure the interest of the developers. For instance, if the number of machines is set at two when it is encrypted, the third machine cannot be installed. The two machines allowed to install can be imposed the number of installation times (from one to infinite).
2. High reliability of key disk. The success rate for key disk installation is nearly 100% (The rate for similar products is about 85%. The very few number of unsuccessful cases can be handled through our unique password installation. Therefore, a 100% success rate could be guaranteed.

In addition, we have taken the lead in solving the problem arising from a failure to read the special sector (key) under Windows95 and 98. So our W32 edition is just as good as our DOS and Win16 editions.
