The number of businesses going online is soaring, so does the risk of data compromise including, data breach, misuse, or exfiltration.
Case in point: During the third quarter of 2024, data breaches exposed more than 422 million records worldwide. It has led countries around the world to enact stringent data protection regulations on businesses collecting, processing and sharing personal information of customers.
With the cyber threat landscape evolving in complexity, the need for data protection has become more pressing.
In this article, we will go through the 7 principles of personal data protection.
What is Personal Data Protection
Personal data protection is a core component of all businesses – large-scale, medium or small-sized. Almost all countries in the World obligates businesses dealing with the personal data of their citizens to implement stringent data protection measures because:
Benefits of Data protection
It’s a Legal Compliance
Citizens hold the right to be confirmed that their personal data is protected and not misused, exfiltrated of breached while its collected and processed by organisations. This is why regulatory standards, like General Data Protection Regulation (GDPR), California Privacy Protection Act (CCPA) etc., mandates organisations to take proactive measures to protect the data they hold.
It’s a legal compliance for organisations failing to which can lead to fines and penalties. For example, for breaching GDPR standards, fines can be as high as 20 million euros or 4% of a company’s annual turnover.
Helps Build Trust
Today, people are more interested in doing business with companies that respect and safeguard their privacy rights. Hence, businesses looking to thrive in today’s highly competitive digital landscape, building trust among customers stands as a strategic imperative. For this, they must implement proactive security measures and ensure no customer data is breached during processing. That said, any mismanagement of data can cause businesses to face serious consequences such as damage to brand reputation that undermines customer trust on them. Businesses that take necessary data protection measures are more likely to crack more deals, win more sales and build trust among their customers.
Prevents Frauds and Cyber Threats
Having stringent data protection measures is a key to locking out scammers from breaching your organisational data.
Saves You Time and Money
The aftereffects of a data compromise can sometimes be severe for some businesses. In 2024, the average total cost of a data breach was as high as USD 4.88M – a jump of 10% over the last year and the highest total ever. Again, failing to handle a data breach according to data protection regulations enacted on a specific region can cause businesses to face fines, penalties or even imprisonment. Make sure you have data protection measures in place to avoid the risks of data compromise.
To ensure safety of customers’ personal data by organisations, different data protection acts are implemented based on the country where businesses operate in. Adopted on 14 April 2016, and came into effect on 25 May 2018, GDPR has long been considered the standard of all data protection acts because of the stringency it imposes on organisations (controllers and processors) when it comes to personal data protection. The regulatory authority of imposing and administering GDPR is the European Parliament and Council of the European Union. GDPR has an extraterrestrial effect, meaning that the regulations hold good on any business – inside or outside the EU or EEA – if they deal with the personal data of the citizens of the EU and EEA.
Let’s go through the principles it’s based on. Almost all data protection laws resonate around these principles.
Understanding Data Protection Principles
Article 5, GDPR sets out a number of principles that organisations as data controllers and processors must adhere to while collecting, processing, sharing or retaining the personal data of the citizens of the European Union and European Economic Area (EEA). in particular sets out seven key principles related to the processing of personal data, which controllers (i.e. those who decide how and why data are processed) need to be aware of and comply with when collecting and otherwise processing personal data.
Lawfulness, Fairness and Transperancy
GDPR mandates organistaions to process the personal data of data subjects lawfully, fairly and ensuring transparency in relation to the data subjects.
With lawfulness, we understand that, all processing activities
: by a data controllers or data processors (if applicable) should be based on a legal basis and in accordance with the GDPR provisions. GDPR describes the “lawful” data processing when:
- Consent: Data subject agrees to specific processing.
- Contractual Necessity: Processing needed for contract performance.
- Legal Obligation: Processing needed by law.
- Vital Interests: Processing to save life.
- Public Task: Processing for public interest or authority.
- Legitimate Interests: Processing for lawful interests, balanced with data subject rights.
With fairness, GDPR mandates organisations to conduct data processing in an equitable manner and cause no breach of the privacy of the data subjects. Data subjects should be kept in the loop when it comes to processing their data. Data controllers should avoid processing if it’s likely to be deceptive, misleading or detrimental to data subjects.
GDPR obligates organisations to maintain transparency in their processing activities and make information available to data subjects in a precise and easily understandable u]language as delineated in Articles 12, 13 and 14 of the Law. With information, GDPR indicates:
- the purposes of data processing
- the recipients of the data,
- data retention periods, and
- individuals’ rights regarding their personal data.
Purpose Limitation
According to this principle, organisations are obligated to collect personal data only for the legitimate purpose specified when data collection takes place. Any further data processing incompatible with the defined purpose would be considered as a violation of the regulation. However, GDPR allows further processing if it’s for publ;ic, research or scientific purposes. In addition, the regulations allows further processing if the new purpose of processing doesn’t contradict with the original purpose and is not incompatible with the initial purpose.
Data Minimisation
The Regulation allows collection and processing of a minimum amount of data that is relevant and necessary to meet the intended purpose determined at the time of data collection. Collecting data beyond what is required is not permitted under the Data Minimisation principle. Practicing data minimisation principle in data collection an processing complements the principles of personal data protection, preventing organistaions from retaining data unnecessarily. With it, GDPR aims to help data controllers limit the volume of data that could be potentially compromised or exfiltrated in the event of a data breach, thereby upholding data integrity and confidentiality.
Please note: The amount of personal data that is ‘adequate, relevant and limited’ is not defined by GDPR. It should be determined by the data controller.
Accuracy
GDPR mandates data controllers to ensure they hold only accurate and precise data and update it periodically if required. In addition, data should be kept up to date. They are required to delete or rectify personal data that are inaccurate or inconsistent immediately. The Law mandates organisations to have clearly defined procedures in place when it comes to correcting, updating or deleting personal data from their record. Thus, they can ensure only clean, high-quality, accurate and consistent data compatible with the defined purpose is being processed.
Storage Limitation
According to this purpose, data controllers are required to retain individuals’ personal data as long as it’s necessary for meeting the purpose of data collection. The Law recommends data controllers to set a timeframe for data deletion and review. Data subjects must be kept informed about the determined data retention period and the criteria used for retaining this data is critical. Enduring transparency in this regard would help prevent data controllers retaining data beyond the timeframe.
Integrity and Confidentiality
Organisations are mandated to implement organisational and technical measures to ensure secure processing of personal data. It is to uphold the integrity and confidentiality of personal data of data subjects. GDPR recommends controllers to update and regularly assess the implemented security measures to ensure personal data is always secured against threats.
Accountability
Controllers must demonstrate that their processing activities comply with GDPR provisions. For GDPR compliance, they need to maintain records of their processing activities, establish clear processes, and implement proactive security measures to lock out scammers. GDPR recommends controllers to appoint a Data protection Officer (DPO) to oversee processing activities and ensure compliance with regulations.
