Grabe na talaga ang nakawan ng CP ngayon no? Anyway, why don't we discuss kung ano ang mga magagandang theft deterrent features to have on a phone. Samsung has a Mobile Tracker feature but what it does is just inform you if a different simcard is inserted on your phone. Dapat merong available na effective theft deterrent feature. Yung bang feature that would stop making the Cellphone as an ideal device to steal.

Bakit ideal nakawin ang cellphone?

1. Madali lang i dispose. Marami gustong magkaroon ng unit. By hook or by crook.
2. Marami pa ring shops ang nag-uunlock, refurbish, nagbebenta etc ng mga galing sa nakaw na unit.
3. Kahit walang lamang pera ang bulsa at pitaka mo, siguradong may cellphone ka.

Marami pang reasons. But I digress.  Smiley Here's my list of theft deterrent features I'd like on a phone. Feel free to add yours no matter how outrageous or impractical they may seem to be. Brainstorming to. All suggestions are considered. hehehe.

1. Dead Man's switch. A password prompt appears on a set schedule. If you don't enter the password, it is assumed that you lost the phone and the phone is subsequently rendered useless.

2. Proximity detector. Mag-a-alarm kung lalayo ang unit sa iyo by more than a meter. Kasi minsan, malalaman na lang natin na dinukutan tayo pagdating natin sa bahay.

Majority ng mga available method is to eventually make a paperweight out of the phone. But kung extreme measures ang paguusapan... mas maganda siguro kung...

1. May lining ng explosives ang unit mo tapos pwede mo ma trigger kung na snatch para sabog ang kamay ng snatcher.
2. Electrified ang casing.

Not advisable kasi kung pincode or security code nga mismo, nakakalimutan ng mismong may-ari. Pagnagkataon, pati mismo may-ari, he/she will render his/her phone useless din hehehehe...

2. Proximity detector. Mag-a-alarm kung lalayo ang unit sa iyo by more than a meter. Kasi minsan, malalaman na lang natin na dinukutan tayo pagdating natin sa bahay.

Eto, medyo maganda to, tapos yung reciever mo, parang nakakabit sa isang keyholder (ala car alam). Ang problema lang siguro is, pag nakalimutan mo i-activate yang feature na yan sa phone mo at nagkataon doon nanakaw. Mahirap naman kasi laging naka-activate, lagi mag-a-alarm yan lalo na sa kamukha kong malilimutin hehehehehe

Naku, baka maging delikado, lalo na pag nalaro ng mga anak mo yung cellphone, nag mis-trigger at sumabog...
2. Electrified ang casing.

Siguro, mas magandang deterent yung ipa-blocklist yung phone, then once na binuksan ang phone, at na-detect ng network na blocklist yung phone, the network itself will send a signal to deactivate the build in fuse inside the ASIC ng phone, then di na magturn-ON ang phone. (Yung ASIC, dapat na ka-cement na sa board para di na mapalitan or the fuse can be sandwiched inside the multilayer board ng phone, yung wala ng provision to bypassed it using jumpers)

hmmmmmm

If theres a will theres a way sabi nga nila....

Ang CP kasi pwede na reformat so useless ang lock by software sa phone pati blacklist... any celphone technician knows how to do that (reviving a blacklisted phone)... Even pass a law on banning it eh mas talamak pa ang smuggling kasi brand new na mura pa! see the CHINA PHONE!!! and take not matibay din sya depende na lang sa gagamit!

what else... puting explosive to a CP is a good Idea but carrying an explosive means that you are a criminal baka makulong ka pa at mamaya mapagkamalan ka pa suicide Bomber!

Hmmmm electic shock on casing.... NO WAY!!! kasi mahilig ako maglagay n CP sa harapan... gets what I mean ! kasi magka hold up man di nila alam na may CP ako sa HARAP... paano kung may kuryente di patay si JUN JUN ko!!!!

tama. di nman kailangan ng deterent. Kung makikita kasi ng magnanakaw na low value ang CP mo eh di hindi na nya pag-iinteresan un.

dapat kasi ang IMEI ng mga mobile units, separate IC nalang na imbedded sa board ng phone.. hindi na pwedeng palitan ng mga unlockers.. o kaya lagyan ng mga GPS receivers and isesend ang coordinates ng location upon request,,xempre special code nanaman yan para hindi mahack ng mga naguunlock..

medyo mahaba habang research toh.. hehe
cguro bago maging solid ang ganitong feature sa lahat ng units, marami munang magsasakripisyo ng libo libong cellphone sa mga snatchers!!

unfortunately, kahit ano pang proposal ang gawin ng mga engineers, mukhang wala sa interes ng mga mobile phone manufacturers ang mag-implement ng theft deterrents sa phones nila.  nakaw man o hindi ang unit, may profit pa rin sila eh dahil almost sure na bibili ulit ng bagong phone yung nanakawan.  same goes for mobile network providers - hindi naman sila nawawalan ng subscriber at for sure kukuha ka ng bagong SIM.  at isa pa dagdag gastos lang sa kanila ang pag-incorporate ng security features sa phones nila.

prudence in using your mobile lang talaga ang pinaka-praktikal na solusyon.  kung hindi ka de-kotse, wag bumili ng mamahalin at takaw nakaw na phone.  awareness din sa paligid pag gagamitin mo in public ang mobile phone mo.

although I love the idea of being able to make your phone explode in the hands of a snatcher.  hehehe.

hellow guys am newbie hre & a cp tech.may solustion nman kong paano mababawasan ang nakawan ng cp. puwede nyo nman ipa block ang cellphone na ninakaw para hindi na ito magamit ng magnanagaw o ng bumili mismo ng cp para magtanda, all u have to do is isulat at e save nyo ang imei ng cellphone nyo just dial *#06# lalabas yong imei nyo dpat ay magkatugma sa imei na nasa likod ng backhousing ng cp, at dapat may tatak na NTC ang cp, so that if ever mnakaw ito puwede nyo na itong ipablock. punta lang kayo sa NTC at ibigay ang imei at model ng cp nyo..yong mga may tatak ntc lang ang puwede ipa block yong mga recon at refurbish ay hindi puwede...

pwede din ang maglagay ng biometrics sa mga cellphones para ang owner lang ang makakapag-activate nito at kailangan niyang itouch ang reader every 10 minutes para maactivate ito.

My celfon theft deterrent? simple lang. I had my name engraved sa body ng phone.
Pag ninakaw man mahirapan sila ibenta kasi ang na engrave na pangalan di na mabura.
Punta kayo sa SM Mega 4 floor merong nag iengrave ng cellphone dyan. Gumagawa din ng celfon tags. I forgot the name of the shop.

eto ang idea ko:

since mga phones is may port (either USB or serial), implement sila ng Keylocking features na embedded sa hardware ng phone (like using Microchip Keeloq technology which looks virtually unhackable/ or very very difficult to hack)... I had been to a seminar of Keeloq by Microchip and very nice ang presentation at encryption techniques...
http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=2074

tapos every 5 days or 10 days magpoprompt ang phone and you need to insert your USB key sa port ng cp to verify na sa iyo ang phone. Smiley
