I think we can use this information in a variety of ways, with the full development of technology and, the increasing production of information. Perhaps you will ask yourself at the outset, but by analyzing the same information stored with the technologies that are considered, we can provide some of the most important solutions too many of the problems that have occurred through the planning of this analysis. Will be possible

It depends. Some companies are not really sure of what they want to look for. So, they want to collect all data they can get. Then they analyze the data and see which set of data is most influential for them. That has been my experience after doing an internship in a lab which deals with lot of user data. 

Storing big amount of user's information is useful if you know how to deal with them.

You can store all the products that clients of a supermarket bought in a day and you can only take partial information beacuse each customer is different than others. In a million of customers, maybe 20 of them bought the same milk and the same coffee, so... can you deduce that there is a relation about these products?

You can discover relations between data, but it is better to be sure what kind of information you are interested in.

Dear Arindam, dear José,

I share the same experience: most of compagnies store a lot of personnal information on their customers and users, with a killer argument: it could be usefull for business. Indeed, sometimes it is.

However, I think this is unfair for users, and potentially dangerous because no one knows who will use these data, because no one knows the future. In the past, mails were opened only in the worst governments. In our world, we open and store all, including this discussion.

There are solutions to make a fair use of personnal data. There are solutions to propose services based on personnal data without storing any data, and thus preserving privacy and more.

May be we have to work on it ?

In my work as policeman in Spain, we manage a lot of information from people. Our database has big security and is forbidden by law to extract information from it.

A policeman can write data in a personal notepad but does not know data from other policeman. In this case, if we do not know how to look for specific data, information exists but it is not useful.

Dear José,

I understand your point. I know that for european countries there are strong legacy constraints to access to personnal data. However, I still think that storing any interaction, position of people is not right.

First, most of these data are stored by compagnies. There are not under the control of police. There is a business for data on an open market. Data are exchanged. In practice, we do not know where are the data.

Second even in Europe, we do not know who will govern tomorrow., and what will be the usage of these data ?

My point of  view is that if we need to store personnal data, the owner is the user. As a consequence the data have to be under the control of users.

Dear Raphaël,

since social networks exists, this control escape from users.

In companies, if you want to access to a new job, your boss can access your facebook, twitter, linkedin, etc, and check who are you and what you usually do.

It is not only a problem about security when people offers freely this kind of information.

José,

You are right. This is not a problem of security. There are two kinds of information:

- public, as this discussion. By the way, for how long time the information extracted from this discussion will be stored ?

- private, such as your position at some timestamps, such as the queries you made, such as the emails you sent...

My point was just to say is that there are some solutions to preserve privacy and business, and that we have to developp this field of research.

Dear Friends and Colleagues of RG

Unfortunately, large technological internet companies, including those that run social media portals, do. They collect and collect large amounts of data about Internet users. They collect data about the users of their portals for marketing purposes, for the purpose of targeting Internet users, to whom they are directed by profiled information displayed on banners.

Large technological Internet companies that gather in their Big Data database systems various information about Internet users on the basis of those collected from various websites, entered by users of social media sites entries, comments, placed banners, searched information build avatars that are equivalent to every user offered on the Internet information services. Often, Internet users notice that after they searched the Internet for information on a specific topic, right after this search on various websites they use, advertisements or products related to what they just searched on the Internet have been displayed on advertising banners. This is an example of the use of collected information in the Big Data database systems on the subject of users of individual websites and web portals via the Internet technology company.

Internet users are usually unaware of how much information their avatar contains. Often internet users are not fully aware of how much information is available about them in Big Data database systems run by the largest online technology companies. on the basis of information collected from various websites and portals about Internet users in Big Data database systems operated by these online technology companies, electronic equivalents of individuals are built in the form of so-called avatars. on the basis of this information, result reports are created in the Big Data database systems of online technology companies, which are sold to other companies interested in a specific target group of clients, to which they direct their offer of products or services.

Large technological Internet companies gather in their Big Data database systems various information about Internet users, even the types of information they currently do not need. According to the researchers of this issue, these companies collect and collect information about Internt users "on stock", ie they do not need them at present, but perhaps they will use this information only for 5 years, when the progress of data processing technology will change the information needs of these companies in the scope of data processing and its use for the needs of advertising campaigns and marketing services offered to users.

Many data show that the largest internet technology companies that run social media portals, search engines, cloud computing information services, instant messaging and other Internet information services gather in their Big Data database systems various information about Internet users using individual information, communication and marketing internet services.

Sure, you are right. Thanks to data processing we can provide a lot of usefull services, saving resources, reducing the energy consumption,...

But, the question is do we need to store private information for providing nice services ?
