Keyless Entry for Your Home?

[johnnymk]

Anyone use this device? Do you like it? What brand?

[DarkFury]

I use one...

It's called "a garage door opener". :D (just be sure to keep your garage house door unlocked for keyless access. :heh: )

[attgig]

I've been intrigued by it too, but won't do it in the city, as it's just asking to be messed with.

I'd want it to go CHIRPCHIRP whenever I locked my house.

:heh:

My condo complex is about finished installing keyless locks on all the outside entrances. Two have already failed. They have a battery pack which is supposed to last for five years. I am just skeptical of making things needlessly complicated. A lock can eventually fail but it is easier to have a locksmith open and is cheaper to replace. They tell us to not get rid of our regular gate keys which means I have to carry another item on my key chain too- the system uses a fob you touch or get close enough to the lock to make it work- no button like a garage door opener and the fob does not need a battery. They are easy to use.

I've found that the fingerprint readers don't work with everyone's finger. I think even when they do work with a given finger they don't seem to work every time. Nothing is more frustrating than needing to get inside quickly and being rejected by a machine.

Battery life has not been a problem but they can cost ~$300 for a good deadbolt.

I've been brainstorming alternatives.

How about a subcutaneous rfid chip so you can just wave your hand in front of the lock?

In general, passive RFID is too easy to hack. Someone brushes up against you with a reader and they can copy your code. I'd rather not have something on me that told the world that I own an RFID key reader at home.

Active RFID powered by your bloodstream?... maybe!

Also, if you wanted to give your neighbors/family the keys to your house you'd have to inject them. ;)

Lastly, they just generally aren't that available on the market. At least residentially.

At my apartment in Korea, we open all of our doors with codes, so I guess that's keyless entry. I just don't bother thinking about it anymore.

That's probably the worst security of all. Even a casual criminal could tape you entering your code over a couple days and from your motions (even if you tried to hide them) generate a subset of possible codes that he could then brute force to gain entry

[ShawnLee]

Maybe, but no one is really that interested around here. Haha.

Retinal scans FTW!!!

Please put your eye up against the door... and hold still for 5, 4, 3, 2,... :eye:

has a product called bright blue we where thinking of switching our locks to at work we now use a program called lock link express III. but there are some serious problems with the product. see below a response i received back from their tech ppl.

my questions:
1. Is the lock database information stored on the flash drive or on the bright blue and only backed up on the flash drive?

If it is stored on the flash drive what do you do when the drive fails?

2. where is the server opperating system stored at and is there


3. Also have measures been taken to prevent against SQL injection?

Their response:

All data is stored on the USB drive. There is a backup function that our end users can run to copy the database to a computer in their environment. The backup routine runs on the bright blue system and then data can be exported to a PC. Most transactions for reads and rights are being performed in the datbase. These transaction are not written to the same memory space on the drive. We have not yet seen degredation of the system due to an overabundance of read and writes. We are monitoring this, but do not know when or if we will hit a limit on the devices in use. The data backups from a PC can be restored to a new memory stick if there is a failure.

The operating system is not stored on the memory stick. It is stored in local memory on the processor board of the system. THe LINUX kernel is independent of the database.

The system is an embedded application. We have not done addiitional hardening to prevent SQL Injection. We have not experienced this at any of our customers. The application is running on an embedded web server and SQL Lite database and we do not foresee that this will be an issue.

Do you not think that would be a potential problem?

[Jeffbx]

PROBABLY not. If the system is fully internal then there shouldn't be a possibility of SQL injection unless someone has physical access to the box - in which case your doors have already been compromised ;-)

I have one of these at the door into my garage.

I was thinking the same thing: http://xkcd.com/538
