+# Abstract
+
+Strengthening user security is one of the main factors to elevate BitShares. Inlight of recent 
+hacking and phishing attempts this becomes even more important. The need for a more sophisticated
+account security preceeded the idea for a finer-grained control of account permissions.
+We propose to add an additional authority to the account, called Custom Active (Permission). The
+permission contains a list of operationid-to-authority mappings that each grant access to the respective 
+operation as if it were the active permission of the account. Additionally, the arguments of said operation 
+can be restricted.
+
+# Motivation and Rational
+
+Any successfull hacking or phishing attempt on any of the web wallets that are powered by the
+BitShares Blockchain is bad publicity. The user needs to be educated in account security, and this BSIP
+aims to ensure all technical possibilities are met while being flexible to allow many use-cases.
+
+Examples:
+ - Witness Key: Only allows update signing key and publish price feed
+ - Trading Key: Only allows limit orders (arguments restricted to desired markets), update margin position and transfers (arguments restricted to certain accounts)
+ - Proposal Update Key: Approve proposals (2FA comes to mind)
+The above list of named keys is nothing that is known to the backend as the backend should have an abstract implementation.
+ The UI should provide a button "Create Trading Key" that properly configures the respective custom active permission entry.
