Truecaller, the popular caller ID app, has revolutionized the way we receive calls. With its advanced call notification system, users can identify unknown numbers, block spam calls, and even receive alerts before answering a call. But have you ever wondered, how does Truecaller notify before a call? In this article, we’ll delve into the technology behind Truecaller’s call notification feature, exploring the intricacies of its system and what makes it so effective.
The Need for Pre-Call Notification
Before we dive into the technical aspects, it’s essential to understand the importance of pre-call notification. With the rise of telemarketing and spam calls, receiving unwanted calls has become a significant nuisance. According to a report by Truecaller Insights, in 2020, Indians received over 31 billion spam calls, with an average of 128 spam calls per user per month. This has led to a growing demand for solutions that can help users identify and block unwanted calls.
How Truecaller Works
Truecaller’s call notification system relies on a combination of user-generated data, machine learning algorithms, and cloud-based infrastructure. Here’s a breakdown of the process:
User-Generated Data
Truecaller’s massive user base is its most significant asset. When a user installs the app, they voluntarily contribute to the Truecaller database by sharing their contact lists and call logs. This data is then aggregated and analyzed to identify patterns andconnections between phone numbers.
Machine Learning Algorithms
Truecaller employs sophisticated machine learning algorithms to analyze the aggregated data and identify unknown numbers. These algorithms are constantly learning and improving, enabling the app to identify new patterns and connections.
Cloud-Based Infrastructure
Truecaller’s cloud-based infrastructure is the backbone of its call notification system. When a call is made, the caller’s phone number is sent to Truecaller’s servers, which then retrieve the corresponding caller ID information from its database. This information is then sent back to the user’s device, enabling them to receive a notification before answering the call.
The Notification Process
Now that we’ve covered the basics, let’s dive deeper into the notification process:
Step 1: Call Initiation
When a caller initiates a call, their phone sends a signal to the nearby cell tower, which is then routed to the recipient’s phone.
Step 2: Signal Interception
Truecaller’s system intercepts the signal and extracts the caller’s phone number.
Step 3: Database Query
The extracted phone number is then sent to Truecaller’s cloud-based database, where it’s matched against the aggregated user-generated data.
Step 4: Caller ID Retrieval
If the phone number is found in the database, the corresponding caller ID information is retrieved, including the caller’s name, location, and even their Facebook profile picture (if they’ve opted to share it).
Step 5: Notification Generation
The caller ID information is then sent back to the user’s device, generating a notification that displays the caller’s name, number, and other relevant details.
Step 6: Notification Display
The notification is displayed on the user’s device, providing them with instant Caller ID information before they answer the call.
Truecaller’s Additional Features
While the call notification feature is the core of Truecaller’s system, the app offers several additional features that enhance its functionality:
Spam Detection
Truecaller’s advanced algorithms can detect and block spam calls, enabling users to avoid unwanted calls.
