Operational principle
Developer program operates on hardware Dog by calling the interface modules of MicroDog, the hardware Dog responds to the operation and returns the relevant data to the developer application program through interface module. Developers application program can judge on the returned value and take corresponding actions. Return of ineffective responses indicate that no correct Dog is available; in this case, developer may choose to stop the running of application program. Simple schematic diagram is shown as below:

3.       Return data

MicroDog development kit offers two encryption options: use obj, dll and ActiveX control or use shell tool directly, please choose an option according to your requirements.

Use obj, dll and Active X object
obj, dll and ActiveX object offers the interface functions for operation of hardware Dog, you can add the calling of these interface functions into source codes of application programs to protect your one or more software and your application programs need to be recompiled. You will set the frequency of calling of the encryption interface in the application software and measures to be taken when no Dog is found. In principle, the more frequently you call and set the encryption interfaces, the more it will be helpful to your prevention against potential hackers from breaking your software protection

Use shell tool
Usage of shell tool is a fast and simple solution for software protection. Unlike interface function that needs to change the source code, it adds a protection layer for your executable application programs automatically. It will automatically check whether the Dog exist when the programs start running or are running. The application programs cannot run if the Dog does not exist.

Shell tool also offers some other options, like evaluation period.

Product Features

MicroDog development kit is applicable to DOS, Windows 3X/9X ME/NT/2000/XP and Linux operating system, it supports all mainstream programming languages and development tools. Main features of MicroDog development kit are as follows:

Microprocessor
With built-in single-chip microcomputer and 200 bytes nonvolatile memory is provided, programs can be written in by special means and solidified single-chip microcomputer can not be read out or written over, all these ensure that MicroDog cannot be reproduced.
Encryption algorithm
Developer can choose an encryption algorithm and customize encryption algorithm factor (256 kinds algorithms, 24 bits algorithm factor, which can have 16000000 kinds variety.).
Anti-sharing
Data sharing device can be antagonized by MicroDog. Moreover, this function can be set by developer.
Anti-tracing
Unique data exchange random noise technology can effectively antagonize the analysis of logic analyzer and attacks of various debug tool and disallow the simulation of data by software emulator programs.
Password
The password of MicroDog can be set by user. If the password is wrong, the data area cannot be read and written.
Journal number
Each MicroDog has a unique serial number called journal number. Software developer can identify each MicroDog by its journal number. Journal numbers of Dogs of same serial number are different.
 AS technology
Combination of API function calling and shell encryption can realize extremely high encryption intensity. MicroDog establishes coincidence relations with the calling of API function inside shell encryption tools. Then, calling of the API function can be run correctly only when the shell exists and the shell itself conceals the calling of API functions.
Cascade
The MicroDog can be cascaded one by one. It is smaller and easier to use.
Support remote upgrade of multiple modules
MicroDog development kit provides developers with methods to modify the setup of multiple modules inside hardware Dogs remotely.
Support LINUX
