Dear Friends,
In my earlier two parts (Part-1 and Part-2) I discussed about some important terms and logics behind my idea so that my friends can understand my point and they can enrich it with their valuable opinions. And in this third point I have started it as "How to find stolen laptop" as this will be helpful for law enforcing agencies and also other civilians.
So lets come to the original point.
I have already discussed in my earlier parts that laptop can't be traced like mobile phones by using its MAC number like IMEI in case of mobile but at the same time you have also learnt from there that MAC is an unique identifier and your duty is to note the MAC address in a separate place for your future need in case of laptop theft.
I think more or less 98% of laptop users go to internet and they use Antivirus for their Laptops and almost all the antivirus are updated through internet and not only that all the paid Antiviruses are either single user or a limited number of users, which means u can install that antivirus in either single machine or a limited number of machine and if the installation crosses the limit it stops to function in those systems/laptops. So I think now you have understood what I am going to say.
Yes my friend I am going to tell about the unique identifier of your laptop has already been registered in the server of your Antivirus during the time of activation and updatation in the net. There is another unique identifier in your laptop. That is hardware serial number and it can't be changed but you can't get it though any command except using tools/softwares like DEFT ,HELIX3 PRO and others and you can't get these easily. But your laptop manufacturer has this in their record. And I think this is also registered in the the server of your Antivirus.
So I want to say my Police friends that don't sent any request to the ISPs about searching of MAC of stolen Laptops in their network but you can send it to the Antivirus companies, who are running business in your country and in this case you must need support from your Government for passing legislation to compel Antivirus Companies to help police if they want to run their business in your Country and at the same time they must supply the hardware serial number of the laptop to their customers in the bill during selling the product.
And if this system is imposed in your state you need not to spend a single penny for using third party software like laptop tracker for tracking the stolen laptop as all the Govt. are liable to see the interest of their citizen and for this Govt. need not to pay a penny for you.
This was the technical part, which can help you but at the same time you can take help of this website. This is good effort of Quick Heal for the netizens.
Waiting for your comments and opinion on this.
Thanking you
Sujit

How to Find The Stolen Laptop Part-2
Dear Friends,
In my earlier post I discussed about IMEI and MAC, the unique identifiers in favour of Mobile phones and Laptops as these are badly needed for searching in case of stolen or missing. MAC has two other names such as Physical Address and Network Interface Card address. The names itself are indicating its function.
In case of mobile it is easy but in case of Laptop its not easy as during communication through internet the ISP receives the MAC address or physical address of last router (It has also MAC or Physical Address or Network Interface Card address) through which the laptop is connected in internet and this is hardly possible to be the MAC of laptop as most of the laptops are connected with internet through data card or company's router or something else like this. As this thing happens as per logic of TCP/IP and practically in networking so the Internet Service Providers can not keep the MAC of laptop and as a result they can't search us like IMEI searching in case of mobile phones.
So what should we do for searching our stolen laptop? Most of the persons will advice to go to police for reporting and police will try to find out through source engaging and the tech savvy persons will advice and take initiative to install laptop tracker softwares in their system by purchasing softwares and they will do their business.
But don't you think that police should also think through some innovative ideas for tracing the laptop by using technological common sense? Yes police should do and in this case Govt. should come forward for the sake of her citizen as Govt. can't force you to purchase 3rd party softwares as they are also liable for your safety and security and they have also some power to pass the legislation in their country. And what the legislation is? Will discuss you in next part after discussing the actual procedure for finding the laptop.
To be continued.....to Part-3..
With Thanks

How To Trace Stolen Laptop Part-1
My Dear Friends,
Hope all of you are well and were well for the last few moths when I was away from you due my other official jobs.
In my daily work I get different type of cyber crime related complaints and other complaints, which are related to daily life and there I used to get complaints like Mobile Phone theft and Laptop theft. In case of mobile theft its easy to trace out the mobiles than the Laptops.
Why easy?
The reason is the Mobile Phones are traced by us through IMEI numbers searching with the help of Mobile Service Providers and this is also possible if mobile phone tracker software is installed in that phone. During purchasing mobile phones the seller note on their bill the IMEI or ESN number of that mobile. But in case of Laptop/Notepad MAC address is needed for searching the laptop/notepad and here lies the problem as most of the laptop users don't know anything about MAC address and not only that the sellers of Laptop/Notepad does not note on their bill during purchase the MAC addresses of the laptop.
What is MAC address?
MAC address is the full form of Media Access Control. So it is the unique physical address of that part of laptop/notepad (i,e:- the media), which is used to for connecting the network. For knowing details about MAC address pl google it.
How to find MAC address?
Finding MAC address or Physical Address ( Another name of MAC address) is different on different operating systems so you are requested to visit here. and then note the MAC addresses in separate place as this will be required if your laptop is stolen.
Can MAC be Changed?
The answer is yes. So now you will definitely raise question to me that if it can be changed so why will you note this in separate place as the criminal may change it after stealing the laptop/notepad. There are many softwares who allow you to change the MAC address in upper layer but they cant change the original MAC address of the system and for doing a trial you pl use TMAC software as per your OS. They can change the MAC and even they can bring back the original MAC so original MAC cant be changed and thats my original point of discussion in Part-2
