Description

Interlock needs an easy way to give members access to the space. It is important however, to maintain the ability to easily remove access punitively or as members choose to leave the group. The ability to keep track of who enters and leaves the space is not only helpful for security, but also could be used creatively.

Plan

Function Testing - Get a simple electronic lock system working:

• Electronic lock or electric strike
  • Need to know the type and size of door/frame we are working with
  • PDF How To Install Electric Strike
• Computer control of the strike
  • Homemade control through serial port w/relay (cheaper, easier to implement than Arduino)
  • Arduino
    • Probably overkill for this system
• Authentication system
  • RFID/Swipe Card/Key Fob
  • Server to manage ACLS (LDAP server? See Infrastructure#Network)
  • Yubikey
  • iButtons - steel chip that requires a contact to transfer
• Audit logging

Second Factor - Additional authentication for extra security:

• Second factor authentication system (pin pad, touch screen pin pad)

Disaster Planning - make sure the system functions appropriately during problems

• Power Outage: Outbound - make sure people inside are not locked in
• Power Outage: Inbound - make sure people outside can't get in during an outage
• Backup: Make sure a physical key is able to access the doors in case the system has a problem

Tweaks and Geeks - Fun non critical additions:

• Twitter bot
  • Tweet hourly updates on who is in the space
  • Tweet when a person enters the space
• IRC bot
  • Regular updates on who is in the space
• Expand security to other items
  • KegBot security
  • Snacks and vending machine
  • Multiple areas within the space

Parts

• Electric Strike (Fail Secure)
  • ebay search
  • kawamall.com
• RFID Reader
  • Parallax Serial RFID Reader
