Friday Squid Blogging: Mimicking Squid Camouflage
Cephalopods – squid, cuttlefish and octopuses – change colour by using tiny muscles in their skins to stretch out small sacs of black colouration.
These sacs are located in the animal’s skin cells, and when a cell is ready to change colour, the brain sends a signal to the muscles and they contract.
This makes the sacs expand and creates the optical effect which makes the animal look like it is changing colour.
[…]
To mimic these natural mechanisms, the team used “smart” electro-active polymeric materials, connected to an electric circuit.
When a voltage was applied, the materials contracted; they returned to their original shape when they were short-circuited.
“These artificial muscles can replicate the [natural] muscular action… and can have strong visual effects,” said Dr Rossiter.
“These materials, and this approach, is ideal for making smart colour-changing skins or soft devices in which fluid is pumped from one place to another.
As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

Ladies and Gentlemen,
I have developed a new approach to password entry which I would like to offer for your consideration. It is called “CerebraLock” and is based on the categorization of items (text or images) into two categories: known and unknown. An access procedure requires you to categorize these items to gain access – only you can do this, since the categorization is only stored in your brain.
It has a one-time setup which involves some effort, but should from then on alleviate a lot of the problems inherent in the current user name / password scheme such as keylogging, phishing etc. There is nothing to memorize and no passwords to change regularly.
I have tied this together with encryption keys such that only the correct access procedure ‘re-assembles’ a usable private key; however, this is secondary to the authentication method.
I am by no means a security expert; therefore I would greatly appreciate an evaluation and feedback by the readers of this blog (or even the Man himself 🙂 Lacking a forum, I have set up a Facebook page – admittedly not the place to go for people concerned about security – as a place to comment.
Please visit the website: http://bitSplit-enterprises.com/HiVaultage.html
It has software for download (Macintosh only, so far,) tutorial videos and other documentation.
I wish to offer this as a proposal for a way out of the authentication mess we’re all in and believe it may have merit and great potential beyond the initial implementation. But I need your help.
Thank you very much!
