Dependencies: Need Java 1.8

To build this project:

• Clone the project
• Compile the java source code

cd  src/
javac consumer_data_privacy_hba/*.java

This is a Secure 2-Party Computation so this project can be executed on 2 different machines as well as on the same machine.

• To run the project on same machine

  • Create the jars for both User1 and User2

   jar cfm User1.jar Manifest.txt consumer_data_privacy_hba/*.class
   jar cfm User2.jar Manifest2.txt consumer_data_privacy_hba/*.class
  

  • Execute the jars by opening 2 shells and executing each jar.
    • Make sure User1.jar is executed before User2.jar.

   java -jar User1.jar "port (e.g: 5000)" "location of the input GENOTYPED datafile" "cMPerFrame(value: 5 or 25)"
   java -jar User2.jar "port (e.g: 5000)" "IP address of the Server (in this case same machine address e.g:127.0.0.1)" "location of the input GENOTYPED datafile" "cMPerFrame(value: 5 or 25)"
  

• To run the project on different machines

  • End users should decide on the roles (Server/Client)
  • User1 is Server and User2 is client
  • User1 should share their IP address and port to bind to the User2
  • Both User1 and User2 should follow the same commands.
  • Make sure User1.jar is executed before User2.jar.

• To run multple test cases on the same machine

  • Modify the TestCases.java file accordingly.

   /*
    * Modify Below Variables Accordingly To Run Tests 
    */
   	String loc = "test_files/case3/";		//directory for test files for Server
   	String loc1= "test_files/case3/";		//directory for test files for Server
   	String csv = ".csv";				//extension of the test file
   	String txt =".txt";				//extension of the test file
   	String results= "input/TestCasesResults.csv";	//results are stored in this file
   /*
    * 
    */
  

  • Compile TestCases.java

   cd  src/
   javac consumer_data_privacy_hba/TestCases.java
  

  • Create the jar

   jar cfm TestCases.jar Manifest3.txt consumer_data_privacy_hba/*.class
  

  • Execute

   java -jar TestCases.jar
  

• Sample Genotypes files are also provided with this project:

  • Genotypes files for Spanish Family and Ancestry Family

     cd input
    

  • Test Files used in the thesis

     cd test_files
