Users are getting advertisements based on their phone conversations

Today we are living in an era in which there is constant surveillance on us through various sources. Among these, there are satellites and various other electronic equipment that we use daily. Some of those apps collect our data in the background.

The Internet has oven us many things but along with that, there are also some scary consequences. Among those consequences, there is also a breach of our privacy. Especially, smart devices are the main culprits that help in such breaches of trust. We are using them daily. We are also giving consent to various apps to access our microphones as well as our contact list as a whole. This data is then sold to advertising companies, who then show advertisements relevant to us on our devices.

These findings have been proved recently by some recent research. During the research, the users were asked whether they see advertisements based on their conversations or not. In return, several users admitted to getting ads based on their conversations, during phone calls. Several users even admitted to getting emails with the relevant products of their choice. On the other hand, some users did not see any such advertisements. Then some users had no opinion on such matters and some did get such ads some and some very times.

The above problem now needs some strict rules or regulations. This can only happen when the government will pass the Personal Data Protection Bill 2019. Once this will gets passed then people will have control over their privacy. The bill will also ensure that the apps need to specify the data which they are accessing. There also needs to be some clarification about the collection of data and their transactions with third parties.

These changes will make sure that the companies whose apps we are using are alert to the way our data is being used by them. They will also need to be careful with the way they handle our data. Then our data will get some protection om the wrong hands. These changes will also bring about some much-needed changes in the data field. The companies will focus more on the protection of the privacy of data. The data will also need some serious protection from outer elements. It is because various attacks are happening nowadays which are affecting various big organizations. In recent times, AIIMS servers were also hacked and there is a demand for 200 crore rupees in cryptocurrencies from hackers to give back control of servers to the major medical organization.

The recent attacks on the data of such major organizations are also asking for some data-related laws in the country. The changes will pave way for the implementation of some better rules for future generations so that their privacy remains in their own hands. These data-related issues will also safeguard the future of the country. Nowadays, data is the real gold. Data now paves the way for development shortly as technology is getting more dependent on the data being collected from users like us.

DBMS-AN OVERVIEW

DATABASE MANAGEMENT SYSTEM

   The collection of inter-related data and several programs that are used to handle the data is known as Database Management System (DBMS). The main aim of DBMS is to store and efficiently retrieve the data from the database. To manage the data in the database, define the structure for storage of information and provide a proper mechanism for manipulation of information. The database system must also ensure the safety of the information that is stored.

DATABASE SYSTEM APPLICATIONS

    Several applications use a database system. Some of the applications are listed below:

  • Accounting: To maintain the data of employees, salaries, and payroll taxes in the company, students in schools, patients in hospitals, database systems are used.
  • Manufacturing: In factories, database systems are used to manage the supply chain and tracking the production of items.
  • In shopping marts: For maintaining customer, product, and purchase information of items, databases are used.
  • Banking: The database systems are useful in maintaining the customer’s account information, loan details and for maintaining the transactions of credit card history.
  • Universities: DBMS is quite useful in maintaining the student details, course details, and accounting in universities.
  • Reservation systems: To maintain the reservation and schedule information, database systems are used in airways and railways reservation systems
  • Telecommunication: For maintaining the records of the call made and generating the bills, DBMS is useful.

PURPOSE OF DATABASE SYSTEMS

  Earlier database systems are created to manage the commercial data. Data are stored in files. For adding new data or updating the data or deleting the data, various programs are written. Separate applications have to be written for the addition of new data. As time evolves, more files and more applications are required by the system. This typical file processing system is supported by an Operating system. In this system, the data is permanently stored in files. It requires different application programs for extracting or adding new information. Before the introduction of the Database Management System (DBMS), the file processing system was in use.

CHARACTERISTICS OF DATABASE SYSTEMS

  • It represents the aspects of real-world applications.
  • For managing the information systematically.
  • Multiple views for representing the data.
  • Operations such as insertion, deletion, and updating can be done efficiently.
  • A logical relationship between records and data is maintained.

ADVANTAGES OF DATABASE SYSTEMS

  • The data redundancy is removed i.e, there is no duplication of data in DBMS.
  • DBMS allows you to retrieve the desired data in an efficient way.
  • Data isolation can be done in separate tables for convenient usage.
  • A simple query language can be used to access the data.
  • In DBMS, the data integrity is maintained.
  • If some operation is performed on the particular data in one table, then the changes will be reflected on the entire database. So, the atomicity of data is maintained in DBMS.
  • Concurrent access to multiple users is possible in database systems.
  • In DBMS, we can also make the user access only the desired part of the data by restricting the access.

DISADVANTAGES OF DATABASE SYSTEMS                              

  • The complexity of database design is high. And it is also time-consuming.
  • If some failure has occurred in either software or hardware, a large amount of investment is needed to repair it.
  • The entire database may get affected if one part of the database gets affected.
  • For converting the file from a conventional file system to a database system, a large investment is needed to buy the required tools and adopting different techniques.
  • More training is needed for the people who design and maintain the database system.
