Abstract

PURPOSE: A method for controlling an illegal copy of a software is provided to prevent a software from being copied illegally and to reduce personnel expenses for monitoring illegal copies of a software. CONSTITUTION: If a user sets up or executes the software(120), an operating system of a computer extracts CD-KEY information and a MAC address(130). The computer confirms whether the computer is connected to a network(140). If the computer is connected to a network, the extracted data are transmitted to a software manufacturing company(145). If the computer is not connected to a network, the data are stored in an auxiliary memory(143). The received packet of the MAC address is analyzed according to addresses(145). The temporary stored data are compared with the currently used database(160). If the MAC address is initially registered, the MAC address and the CD-KEY are newly stored in pre-stored database(163). If the MAC address is not initially registered, the MAC address and the CD-KEY are compared with all existing data(165). If the MAC address and the CD-KEY are identified with the existing data, the copying process is judged as an illegal copying and a proper management is performed(175).

Description

Software piracy enforcement method using MAC address and user authentication number (CD-KEY) when using software {omitted}

The present invention relates to a software (simply referred to as S / W) piracy control method, more specifically, the MAC address and user authentication number (generally called CD-KEY, which is transmitted when using the software, and then CD). -KEY means user authentication number).

In the past, many technologies have been proposed for preventing illegal copying of S / W.

Put a unique CD-KEY to prevent indiscriminate copying, or go to the S / W company or organization to search for computers one by one to crack down on illegal copying, or use IP and CD-KEY (Public Patent Publication 10- 2001-0025298) has been proposed.

However, these prevention laws are mainly limited to corporations or organizations, and there is a limit of enormous labor costs in case of direct enforcement.

The patent publication may be relatively useful for fixed IP, but may not be useful for floating IP. An individual can have as little as a few hundred to as many as a thousand IPs at an Internet Service Provider (ISP) company. Storing all of these dynamic IPs on the server of the S / W production company is not only a waste, but also a problem that can be pointed out that the cost may rise and cause the industry to lose competitiveness.

The present invention has been made to solve the above problems to provide a S / W enforcement method through the Internet to prevent illegal copying of S / W, save labor costs involved in enforcement.

1 is a network diagram for illegal software enforcement according to the present invention

Figure 2 is a flow chart of the S / W enforcement method by the MAC address and CD-KEY when using the software according to the present invention

The present invention for achieving the above object is the process of automatically extracting the CD-KEY and MAC address, which is embedded information of the S / W when the software is installed or executed, the process of transmitting it to the S / W manufacturer, and this information Compare and search to distinguish whether or not illegal S / W, and characterized in that the process was taken.

The MAC address (Media Access Control Address) used in the present invention is as follows. TCP / IP proposes a method for recognizing the source and the destination computer for additional control information, which is a physical address.

Just as an address is required to deliver mail, and a phone number is required to make a call, a computer needs a number called a MAC address to communicate with. A MAC address, also called a physical address, is a number uniquely assigned to each port of a network device such as a LAN card and used to identify a communication partner in data transmission. The MAC address is charged with the control head at the datalink layer of the OSI reference model layer 2. In other words, the transmission frame we send and receive includes two MAC addresses representing the receiving side and the transmitting side. This MAC address is of the form:

In our country, more than 40% of computers are connected to high-speed Internet. And if you think about modem accessors, more than 60% are already connected to the network, and this trend will grow, and in the near future, computers will naturally exist for the Internet. .

In this process, as mentioned above, if the PC we use is private, corporate, organization, fixed IP or dynamic IP by ISP company, we want to connect NIC (Lan Card, etc.) unconditionally. The device has its own unique MAC address.

The present invention is physical and cannot be converted by a user, and is also used to distinguish each computer using this MAC address having a unique number worldwide, so as to distinguish it from the existing IP.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a network for illegal software enforcement according to the present invention. As shown in Fig. 10, the user connects a LAN card having a unique MAC address to a PC and is connected to the Internet network 30 by an Internet service provider (20: ISP company). And this network is connected to 40 S / W manufacturers' servers.

2 is a flowchart illustrating a S / W enforcement method using a MAC address and a CD-KEY when using S / W according to the present invention.

First, let's look at the execution process on our PC (110-145).

When you set up or run S / W (120), the computer's OS can use the functions built into the OS itself, or by using S / W, or by S / W designed for the above process. Extract key information and MAC address (130).

At this time, the computer checks whether the computer is connected to the network after the execution process (140), and if connected, transmits the data extracted in step 130 to the S / W production company (145), and if it is not connected, the user In case of malicious termination of the network, one day, the computer waits for the computer to connect to the network, and the auxiliary memory device records the data to be sent to the S / W manufacturer and sends it later (step 143).

Using the above process, a computer connected to the network will one day transmit a CD-KEY item and usage information about the S / W on the computer to the S / W manufacturing company. (145) (The MAC address to be sent is the own PC. It is inherently embedded in the packet to the S / W production company as the source of the eigenvalue of, so no additional allocation is necessary.)

Now, the role played by S / W production company server is as follows. (150 to 180 courses)

The received packet is analyzed for each MAC address (145). Here, the MAC address is physical and unique, and CD-KEY information is read based on the unique value.

Then, the temporary stored data is compared with the existing database as the MAC address. (160) If the MAC address value is the first registered value, the MAC address and the CD-KEY value are newly updated in the previously stored database according to the example. Save (163)

If the value above is not the first value registered, it is compared with the existing database. (165)

In case of matching with existing CD-KEY, this means that two users use the program with the same unique number. This means that it is illegally copied S / W and asks the ISP company for MAC address. Will take appropriate action according to company regulations. (175)

On the other hand, if it does not match, it is a genuine S / W user and ends. (180)

Software companies can take damages from piracy, and enforcement agencies and companies can skip complex processes, such as having to spend all their money on hardware to check for illegal software, and try to develop the software industry. Can be.
