Unveiling the Distinction: Privacy is Not Security

Devansh Tayal — Mon, 07 Aug 2023 15:34:32 +0000

In an era where personal information is more valuable than ever, the terms "privacy" and "security" are often used interchangeably. While they are undoubtedly interconnected, it's important to understand that privacy and security are distinct concepts, each with its own set of implications and considerations. In this blog post, we'll delve into the differences between privacy and security and shed light on why one cannot be a substitute for the other.

Before choosing the right attribute between the Security and Privacy, let us understand the meaning of both with an easy example.

Buying the Antivirus gives us the security options like web-plugins, password manager, malicious website blocker etc. Our Security gets improved but our Privacy got drained. We are putting our trust in a third party apps that is scanning every file that is in our storage, every program we download, we open, that app has an eye on all of our activities

Defining Privacy and Security
Privacy refers to the right of individuals to control their personal information and the extent to which that information is disclosed to others. It involves the management of data in a way that respects an individual's autonomy and ensures that sensitive information is handled with care.

Security, on the other hand, is the practice of safeguarding data, systems, and assets against various threats, such as unauthorized access, cyberattacks, or physical breaches. Security measures are implemented to prevent, detect, and respond to potential risks.

Focus and Scope:
Privacy: Primarily centers around the individual's control over their personal data, including its collection, use, and sharing.
Security: Concerned with protecting data and systems from a wide range of threats and vulnerabilities, both internal and external.

Objectives:
Privacy: Aims to empower individuals with choices regarding their personal information, promoting transparency and consent.
Security: Strives to ensure the confidentiality, integrity, and availability of data, reducing the risk of unauthorized access or data breaches.

Measures:
Privacy: Involves practices such as data minimization, informed consent, and transparency about data handling practices.
Security: Encompasses encryption, access controls, firewalls, intrusion detection systems, and incident response plans.

Impact:
Privacy: Affects individuals' trust, autonomy, and perception of how their information is treated by organizations.
Security: Mitigates risks and prevents potential damages, maintaining the stability and operations of systems and data.

Why Privacy is Not Security
While privacy and security are intertwined, they address different dimensions of data protection. Focusing solely on security measures does not necessarily guarantee privacy, and vice versa. Consider a scenario where a company implements robust security protocols to safeguard customer data. While these measures protect against external threats, they may not address concerns about how the company uses or shares the collected data with third parties, affecting the privacy aspect.

Moreover, breaches of privacy can occur even in the absence of security breaches. An organization might misuse or mishandle personal data without any external attack on its systems. Conversely, a security breach may involve unauthorized access to systems without necessarily exposing private information if data is encrypted.

Striking the Balance
The key lies in striking a balance between privacy and security. Organizations should adopt comprehensive strategies that encompass both aspects. Effective privacy practices enhance an individual's trust in the organization's security measures, while robust security measures provide a foundation for maintaining privacy.

Conclusion
Now, want to be Secure or Private?
From my perspective, it is not possible to move with either Security or Privacy. It is very much important to have Security as well as Privacy measures at the same time in the 21st century.
We can achieve security without Privacy but privacy cannot be achieved without Security

What is the worst-case time complexity of the following algorithm to delete the node from the list?

// Find next node using next pointer
struct node *temp = node_ptr->next;
// Copy data of next node to this node
node_ptr->data = temp->data;
// Unlink next node
node_ptr->next = temp->next;
// Delete next node
free(temp);

a) O(n)
b) O(log2 n)
c) O(logn)
d) O(1)

(d)
Explanation: It is a Fast solution to delete a particular node from the linked list is to copy the data from the next node to the node to be deleted and delete the next node.Time complexity of this approach is O(1).

Btech percentage doesn't matter is a myth. Let me explain with 3 reasons!

Devansh Tayal — Sun, 28 Feb 2021 14:29:22 +0000

Let's say 2 students, Ram and Shyam go for placements, Ram has 86% and Shyam has 65%. (#Reason1 if you don't have at least 65% you won't be able to appear even for written)

Ram-Shyam both clear written and reach the interview round, whom will the interviewer appreciate more? (#Reason2 higher percentage gives you edge in interviews)

Shyam's low percentage will not matter only if he has a solid coding profile (Codechef, Codeforces etc) or he has a solid dev profile (GitHUB, Full Stack).

Or if Shyam is able to give satisfactory explanation when interviews asks why he has low percentage?

Net net, in on-campus you can get selected with low percentages as well but having higher grade will not harm either!

Reason3

For off campus, surely percentage is a key criteria for companies to shortlist/prioritize among thousands of applicants.

I know its not a perfect criteria, but it is not going to change at least by the time you appear for placements. So morals are good but you need to be practical as well.

Let me know what you think

Something for open source

Everyone has heard of Gsoc when it comes to open source. To be true it's not easy if you are really a beginner. But the another program "Hacktoberfest" , the yearly event of october where one can participate who is really a beginner. If even learning the git/github or like how to make contributions you can sign-up for the program. It gives swags too which might be a motivation for a beginner.

Hacktoberfest 2020

What I Learned From Hacktoberfest

Its not necessary to have knowledge of everything when you work in open source. I learn when I work. I bring the bottom-up approach to contribute. Well, I reviewed the code for cpython and was a contributor to Python Turtle(the learning platform for python). Moreover I found the community really responsive and helpful. The guys with great status are communicating and were helpful to me. I learn a lot from them.
