Area Based Service (LBS) turns out to be progressively famous with the sensational development of cell phones and interpersonal organization administrations (SNS), and its setting rich functionalities draw in extensive clients. Numerous LBS suppliers utilize clients’ area data to offer them accommodation and valuable capacities. Nonetheless, the LBS could enormously rupture individual security since area itself contains much data. Subsequently, safeguarding area security while accomplishing utility from it is as yet a testing question now. This paper handles this non-unimportant test by outlining a suite of novel fine-grained Privacy-saving Location Query Protocol (PLQP). Our convention permits diverse levels of area inquiry on encoded area data for various clients, and it is sufficiently effective to be connected in versatile stages.
Existing System 
The least difficult way, which the vast majority of uses received, is to apply amass construct get to control in light of distributed areas: indicate a gathering of the client who can or can’t see them. Social photograph sharing site Flickr just let clients pick all clients, neighbors, companions or family to enable the entrance to the areas, and SNS sites Facebook and Google+ moreover bolster custom gatherings to indicate the available client gatherings. Portable applications are much more awful. Numerous versatile applications (e.g., Circle, Who’s around and Foursquare) even don’t offer to gather decisions to the clients, rather, they just ask clients whether they need to uncover the area or not. Clearly, this is excessively straightforward, making it impossible to accomplish what clients require. As a matter of first importance, from clients’ viewpoint, it is difficult to unequivocally decide a client gathering with the end goal that their areas are obvious just to them. It is more normal to discover a condition to such an extent that companions who fulfill it can or can’t see the area. Also, double access control (can or can’t) is long ways sufficiently past to legitimately design the security setting. In the past case of the two sweethearts Alice and Bob, Alice might need to impart her date at the eatery to her closest companions and reveals the correct area to them. Additionally, Alice may likewise need different companions to realize that she is enjoying herself in downtown, however not nitty-gritty area. For this situation, rough settings amongst ‘can’ and ‘can’t’ are expected to satisfy her necessities.
As examined above, existing security control settings in LBS are ‘coarse’ as in 1) clients can just unequivocally determine a gathering of clients who can or can’t get to the area data; 2) get to control approach underpins parallel decisions just, which implies clients can just empower or handicap the data divulgence. The current control systems additionally experience the ill effects of protection spillage as far as the server stockpiling.
Proposed System: 
In this undertaking, we propose novel conventions with the end goal that the area distributor applies a fine-grained get to control on who can get to what area data. For instance, a distributor could determine the accompanying access control strategies: (1) a client can know which city I am in if s/he is in my companion rundown; or (2) a client can check whether the separation amongst him and me is under 100 meters if s/he is my cohort; or (3) a client can figure the correct separation between us on the off chance that we both went to a similar college.
Favorable circumstances:
Practical Encryption is an encryption plan with the end goal that a key holder can take in a particular capacity of the information in light of the ciphertext, yet nothing else about the information. This is entirely unexpected from the conventional encryption plot regarding the separated decoding.
1. Fine-Grained Access Control.
2. Multi-leveled Access Control.
3. Privacy-Preserving Protocol.
4. Euclidean separation.
Modules Description
1. Fine-Grained Access Control
Our convention enables clients to determine a condition rather than a gathering and apply get to control the clients who fulfill this condition. This is more versatile since clients can basically include another condition for new protection setting rather than hand-picking several clients to shape another gathering. Additionally, this is all the more user-friendly on the grounds that clients themselves don’t unmistakably know which of their companions ought to or ought not to get to the data the greater part of the time.
2. Multi-leveled Access Control
The convention likewise bolsters semi-utilitarian encryption. That is, the convention empowers clients to control to what degree (or level) others can take in this area. The least level compares to nothing, and the most abnormal amount relates to one’s correct area. Levels between them compare to aberrant data about one’s area.
3. Privacy-Preserving Protocol
In our convention, each area data is encoded and questions are handled upon ciphertexts. Along these lines, an area distributer’s companions get the hang of only the consequence of the area question, which is under the area distributer’s control. Furthermore, since each area is scrambled, even the server who stores area data does not take anything from the ciphertext.
4. Euclidean separation
For straightforwardness, we expect a ground surface is a plane, and each client’s area is mapped to a Euclidean space with number directions (with a meter as a unit). That is, everybody’s area can be communicated as a tuple of directions speaking to a point in a network parcel of the space. This does not influence the sweeping statement since there exists a bijection between round areas and Euclidean areas. By approximating the directions in the Euclidean space to the closest matrix point, we can demonstrate that it brings about mistakes of the Euclidean separation between two areas at most √2 meters when space is parceled utilizing lattice of side-length 1 meter.
