A PPT on what proprietary licenses are? Why use proprietary licenses? What are trademarks? What are Trade secrets? Reverse Engineering and Obfuscation

1. PROPRIETARY LICENSES AND
TRADE SECRETS
Open Source Technologies

2. WHAT PROPRIETARY LICENSES ARE?
• No Source Code disclosure*
• No Modifications allowed
• No Redistribution allowed*
• Can be commercial or free
• Restrictions on usage through EULA
• E.g.: OSX, Windows, Adobe Reader, Google Earth etc.
*Conditional

3. WHY PROPRIETARY LICENSE?
• Commercialization
• Prevention of Decompilation

4. TRADEMARK™
• To brand a product
• Identify a product as of a company or group
• Value matters
• Anyone can register
• May brand over a couple of years
• E.g.: Coca-Cola ™

5. TRADE SECRETS AND NON-
DISCLOSURE AGREEMENTS
• Hiding Product Information
• Enforced on employees by agreements and confidentiality
• Non-Disclosure agreement – Threatens penalties
• Employee can’t use information received after leaving
• Violators can be imprisoned or fined
• Trade secret allows hiding crucial information over Patents

6. REVERSE ENGINEERING AND
OBFUSCATION
• Reverse Engineering is figuring out how something works
• Black box and White Box Reverse Engineering
• RE is Counter Balance to Trade Secrets but laws defends
• The Clean Room or Chinese Wall approach
• Decompilation is getting object code through source code
• Obfuscation prevents Decompilation
• Obfuscation implements behavior but scrambles code

7. TYPES OF PROPRIETARY SOFTWARE
• Freeware – Free for personal use* and not for redistribution*
• Shareware – Trial period based software and no redistribution
• Liteware – Shareware that omits many functions and support
*Conditional
