public class BogusInitializer

extends StaticWatermarker

Algorithm Implemented by : Ashok Purushotham & RathnaPrabhu emails : ashok@cs.arizona.edu prabhu@cs.arizona.edu This algorithm adds a constant "sm$len=x" where x is the number of bogus initialisers to be embedded in the constant pool of a random class. sm$len is the identifer we're looking for during recognition and based on the value , we will looking for that many bogus initialisers embedded Important : THE INPUT JAR FILE SHOULD NOT CONTAIN ANY INTERFACES OTHERWISE, getInstructionList will return null

static int bogus_ids_no

Constructor Detail

BogusInitializer

public BogusInitializer()

Constructs a watermarker.

Method Detail

getShortName

public java.lang.String getShortName()

Returns this watermarker's short name.

Specified by:

getShortName in class Algorithm

Returns:

the short name for this algorithm

getLongName

public java.lang.String getLongName()

Returns this watermarker's long name.

Specified by:

getLongName in class Algorithm

Returns:

the long name for this algorithm

getProperties

public static ConfigProperties getProperties()

Description copied from class: GeneralWatermarker

Get the GENERAL properties of watermark

setProperties

public static void setProperties(ConfigProperties props)

Description copied from class: GeneralWatermarker

Set the GENERAL properties of watermark

getAlgHTML

public java.lang.String getAlgHTML()

Description copied from class: Algorithm

Gives a description of what the algorithm does. This should not be a long description of what your code does, rather a brief description as to what effect it has on the program. For example, a good algorithm description would be "Set Fields Public changes the scope of all static and non-static fields to public."; a bad algorithm description would be "Set Fields Public creates a BCEL object for each class and makes modifications to it, then stores it back into the jar file."

Specified by:

getAlgHTML in class Algorithm

Returns:

an HTML formatted description of what the algorithm does.

getAlgURL

public java.lang.String getAlgURL()

Description copied from class: Algorithm

Specifies the URL of where the user can find more information about the algorithm. This URL should point to the help.html file in the doc directory where the algorithm resides, starting from the sandmark directory. For example, the URL for the static_template watermarking sample would be sandmark/watermark/static_template/doc/help.html

Specified by:

getAlgURL in class Algorithm

Returns:

a URL to the help.html file for the algorithm

embed

public void embed(ClassFileCollection cfc,
                  java.util.jar.JarOutputStream output,
                  java.util.Properties props)
           throws WatermarkingException,
                  java.io.IOException

Description copied from class: StaticWatermarker

Embed a watermark value into the program. The props argument holds at least the following properties:

• WM_Encode_Watermark: The watermark value to be embedded.
• SWM_Embed_Key: The secret key.

Specified by:

embed in class StaticWatermarker

WatermarkingException

java.io.IOException

recognize

public java.util.Iterator recognize(java.util.Properties props)
                             throws WatermarkingException,
                                    java.io.IOException

Specified by:

recognize in class StaticWatermarker

WatermarkingException

java.io.IOException

setConfigProperties

public void setConfigProperties(ConfigProperties props)

Description copied from class: Algorithm

Sets the ConfigProperties object which specifies the parameters for this run of the algorithm.

Specified by:

setConfigProperties in class Algorithm

Parameters:

props - the parameters for this run of the algorithm

getConfigProperties

public ConfigProperties getConfigProperties()

Description copied from class: Algorithm

Gets the ConfigProperties object which specifies the parameters for this run of the algorithm.

Specified by:

getConfigProperties in class Algorithm

Returns:

the parameters for this run of the algorithm
