Create a temporary phone number with inumbr

Maybe you don’t want that one person that has barged into your life to know your private phone number? Could be a salesperson or a co-worker who you aren’t that impressed with, but have to get in contact with. Check out inumbr.

inumbr is a free online service that gives US users the ability to set up a unique phone number, have it forwarded to any number within the US and then have it set to expire without a trace when finished with it. The unique inumbr’s are never reused, and can be extended if longer terms are required. Users choose from a list of 22 area codes from major US cities like Chicago, Los Angeles and New York, select an expiry date and set a number that it should be forwarded to. When the term is up, the number is expired from the system, and never used again for any other user. If you wish to use the number at a later date, you can log into the inumbr system and reactivate it.

As we are becoming more and more mobile and security conscious, the desire for these types of services grows. A phone number can now be given out at will, with security and privacy remaining intact. Google Voice is a major player in this arena. A somewhat similar service, they allow for a unique number with voice mail to forward to other numbers at will, creating a masked or unidentified private number that can be used to give out to 3rd parties. inumbr makes this process simpler with the ability to cut off and reactivate numbers as desired.

The EFF’s privacy agenda


With a new administration coming into power, the Electronic Frontier Foundation feels that it’s time for a change (see what we did there). They’ve posted an agenda that covers fixing privacy issues that have come to the forefront in the last eight years. It involves repairing amendments that prevent corporations from being sued for warrantless wiretapping. They would also modernize the Electronic Communications Privacy Act so that it would cover modern technology. The heavily abused State Secrets Privilege needs reform as well. Their final issue is with REAL ID and datafarming that many state governments have already rejected. If even a bit of this gets fixed, we’ll be happy. In any case, it’ll be good to have a more tech focused administration that doesn’t need the internet explained to it in terms of dumptrucks and tubes.

Pirate Bay hits the road, angles for encryption

Piratbyrån and their hearties from The Pirate Bay are on a pan-European summer journey that will end at the Manifesta art biennial in Italy, but in the meantime they’ve been hard at work lobbying for total network encryption, a system that would protect users of a network (say, a P2P network) from deep packet inspection and other forms of activity analysis.

The system by which this will be achieved is called IPETEE, and it works by replacing the basic operating system network stack and doing all encryption and decryption itself. More details can be found in the IPETEE technical proposal.

Ars Technica pointed out numerous holes in the scheme, noting that most torrent apps already have encryption options. IPETEE applies to more than just torrents, though, so the larger problem is that encrypted packet still need source and destination IP addresses, meaning that one of the most crucial things you’d want to keep private (your destination site) is still accessible.

OpenBeacon: Active RFID Platform

The OpenBeacon project is an open source hardware and software active RFID device. OpenBeacon tags consist of 2.4GHz transceivers and a PIC16F684. One use of the project was to create CCC Sputnik to show the downsides to information culled using data mining from large tracking systems. People who chose to participate and wear the Sputnik tags did so voluntarily to create a database of material for further study. The hardware schematics (PDF) for the first version tags as well as the firmware for all versions has been released. Further creative uses of the OpenBeacon project are strongly encouraged.

As a reminder, the 24C3, the 24th Chaos Communication Congress, call for participation ends on October 12th. The theme this year encompasses all hardware projects and more specifically, steampunk themed submissions. Check out the CCC events blog for more information.
