1 Jon Bing Proving Copyright Infringement of Computer Programs – Some practical Examples

2 Developing a computer program

3 Co-operation in developing a program

4 «One» program

5 User interface

6 Strategies in identifying interesting source code extracts
Sorting on file names Sorting on file seize Indexing – inspecting variables identical or similar Calculating a hash value for each line of programming code

7 Comparing source code SJEKK-AVGR. MOVE 0 TO SJEKK SJEKK-10.
SJEKK-10. IF WS-FRA = 0 AND WS-TIL = 0 GO TO SJEKK-20 IF WS-FRA NOT < WS-FRA1 AND WS-FRA NOT > WS-TIL1 GO TO SJEKK-TILSLAG. IF WS-TIL NOT < WS-FRA1 AND WS-TIL NOT > SJEKK-AVGR. MOVE 0 TO SJEKK SJEKK-10. IF WS-FRA = 0 AND WS-TIL = 0 GO TO SJEKK-20. IF WS-FRA NOT < WS-FRA1 AND WS-FRA NOT > WS-TIL1 GO TO SJEKK-TILSLAG IF WS-TIL NOT < WS-FRA1 AND WS-TIL NOT > GO TO SJEKK-TILSLAG.

8 External factors Programming language Standards Best practrice guides
Boiler-plate text Third party components

9 Incremental development

10 Development process Time and resources used for development Experience

11 Pro-active strategies
Clean room procedures Full documentation Original when possible (name of variables as an example)
