How To Secure Police Data With A DEMS Solution?

With the police holding access and custody of confidential data from several resources, mechanisms need to be implemented to secure such information. 

Policing is no easy task. Police officers working on cases of all sorts are pressured with the responsibility of data collection and analyzing from various sources.

Police departments also hold the liberty of demanding data from sources such as private CCTVs, websites and online databases, medical and legal records, and other resources, based off a warrant or suspicion; a topic upon which Signal shed light as they spoke on how far law enforcement will go for information collection.

This may vary to a certain extent based off differences in regional laws, but in general it is an established fact that the police have access to collect from most data resources around.

But now the question that comes into play is about data security. How secure is data in the hands of the police? And what measures are taken to keep police data secure from potential incoming threats?

This is what we are about to entail in this blog, so read on to know more!

What Purpose Does Data Collection Serve For The Police?

Police forces today make use of data from each possible relevant source to a criminal case to determine if a suspect is to be arrested and detained.

Each bit of data collected serves as a piece of evidence for that particular case. Evidence, which in our case of consideration is digital, must be protected from any form of tampering and modification.

In order for it to be it permissible to be admitted in court and other legal proceedings, the evidence must be retained it in its original, unaltered state.

How To Secure Police Data To Retain Evidence Integrity?

In order to retain such originality, the evidence data must be kept secure with measures protecting it from internal and external threats.

For physical evidence, physical security measures are the only option to go for, with retention measures specific to the nature of the article of evidence, such as to retain food or perishables.

However, digital evidence, being an intangible resource stored on both physical storage mediums and online on the cloud, calls for a different set of parameters to be taken to prevent it from being spoliated or rendered inadmissible for legal proceedings.

What Are The Best Practices & Measures Enforced To Secure Police Data Digitally

Digital evidence, like any other form of digital data, exists as an intangible form of information stored on a local storage medium on-premises, or online on a cloud-based provider’s remote server.

The choice of storage and deployment varies based upon the organization’s use case and other factors. Often, law enforcement does not prefer deploying over the cloud but rather go for keeping data within their own datacenters.

Regardless of where it is stored, the data needs to be secured. Certain measures need to be taken that offer security for any form of digital data but are obligatory when it comes down to dealing with confidential information such as digital evidence.

Legal Compliance

There are several legal compliances in place that regulate matters such as protection of digital information, its privacy, admissibility, withholding, and permissibility to share.

Notable names include GDPR, the CJIS, the CRoC, FedRAMP, HIPAA, FOIA and others.

These compliances help in fulfilling the rights of citizens as well as act as a source of maintaining police integrity and moral authority of individuals.

Complying with the clauses of these legal compliances often secures the data in many ways, as these compliances often impose mandating upon elements such as PII redaction.

Learn more about compliances on our article concerning the relationship between Police and GDPR, along with several others that you may find on our blog site.


Hashing of data is one of the most important countermeasures taken to prevent data manipulation and corruption, and to prevent such occurrences from going undetected. A hash function turns a value of understandable information into its corresponding hash value.

The benefit of using hash functions to secure information is that if information is tampered with, the value can be used to trace back the data and detect tampering. This proves to be especially useful with data such as digital evidence where integrity plays a key role.

SHA (Secure Hashing Algorithm) is one of the most used hash functions, of which SHA-3 is the most secure. Other alternatives include SM3, MD5, BLAKE2, and Whirlpool.

SHA-3, or SHA-2 being the bare minimum, is the norm for all solution providers for law enforcement to secure police data and other information.


Encryption is one of the primary shields against data theft. Encrypted data proves to be useless without the right cipher to decrypt it. Encrypted data, or cipher text, is of no use until it is converted back into its original form using a cipher key.

Several encryption methods exist, including the simplest Caesar’s cipher to the 256-bit AES cipher.

AES-256 cipher encryption provides optimal security for data, which explains why it is the ideal choice of today for data encryption requirements in most domains, such as law enforcement.

Redaction is a core necessity presented by several legal compliances. This is because it ensures data protection of individuals that are not involved in an incident to be excluded from proceedings.

Redaction of faces and other PII data allows police officers to securely share data with public bodies such as courts and the press.

Here’s our Detailed Guide on Redaction to help you understand it better.

Without redaction, public disclosure of PII information and other confidential critical information can lead to severe consequences, such as lawsuits.

Access Restriction

Consider case files of higher profiles and confidentiality, such as those involving government bodies, influential individuals, or minors. Such cases and their contents are not open to access for all police officers, except for higher authorities of the department and law enforcement directly involved in a case.

Thus, for a system to segregate data amongst the individuals using it, the system must allow the user to take certain measures. For instance, user roles should be distinctively defined to allow access restriction to files based on these roles.

Portal based segregation of data also paves way for easier segregation of case files and data between multiple departments of an organization.

When sharing files, such as videos for court proceedings, access restriction can be established through multiple sharing controls, such as passwords for shared content and restriction of access of content to be limited to the recipient only.

These are some of the primary measures than can deter most of the security threats posed to police data. However, independent implementation of each can be a hassle for police forces.
