This article explores the rise of appointment scheduling theft, its impact, and how public institutions can protect themselves—and their citizens—with smarter, secure scheduling flows.
In today’s digital-first world, institutions must offer services that are fast, accessible, and secure. To meet these demands, many now rely on online booking pages that allow citizens to schedule appointments efficiently. But an invisible threat is putting that trust—and those services—at risk: appointment theft.
From consulates and visa offices to city halls, bots are stealing appointment slots intended for the public and reselling them in underground markets. These bots exploit vulnerabilities in the booking experience, making it difficult for genuine users to book appointments. This is no longer an isolated issue—it’s a growing trend that directly threatens public service delivery.
The consequences are serious: frustrated citizens, disrupted operations, and a gradual erosion of trust in public institutions, as the normal schedule and booking experience are compromised.
This article explores the rise of appointment scheduling theft, its impact, and how public institutions with multi-location offices can protect themselves—and their citizens—with smarter, secure scheduling flows.
The problem came to widespread attention when the Munich Immigration Office reported alarming patterns:
Bots Got There First
These attacks can lead to scheduling conflicts and disrupt the institution's calendar management, as bots can fill up available slots, interfere with calendar syncing, and make it difficult to maintain an accurate and conflict-free schedule.
Despite the introduction of traditional security measures—such as CAPTCHA checks and email confirmations—attackers adapted quickly. Even features like automated confirmations and calendar syncing are sometimes circumvented by sophisticated bots. A relentless cat-and-mouse game emerged between bot programmers and IT teams.
At stake is more than IT integrity—public trust is on the line.
Legacy Systems, Modern Threats
Several factors make public institutions an attractive target:
Unlike private businesses that can adjust services dynamically, public sector institutions must balance accessibility, transparency, and fairness. That makes defending appointment systems even more difficult.
At the heart of the issue is a simple need: fair, secure, and predictable access to public services.
Appointment theft isn’t just a technical issue. It creates real-world consequences that ripple across the institution:
The good news? Institutions can take steps now to prevent these consequences.
At TIMIFY, we understand that securing appointment systems is a complex challenge—especially when citizen access must remain simple and fair.
That’s why we’ve developed the TIMIFY Secure Citizen Scheduling Flow: a multi-layered approach tailored for the needs of public sector clients. Our platform functions as advanced appointment scheduling software and booking software, enabling institutions to accept bookings securely and efficiently.
While each implementation is customised to the institution’s infrastructure, here are some of the core security layers we can provide, including advanced features such as real time availability and customizable availability settings to further enhance security and user experience:
Validation Starts at the Source
Every booking requires a verified mobile number, validated in real time through modern techniques like SIM-swap detection and call diversion analysis. Identity checks are handled in the background without friction to the citizen.
One Slot, One Citizen
Based on one or more unique identifiers, institutions can limit the number of appointments each citizen may book per month—closing the door to mass booking attacks.
No Confirmation, No Entry
A booking isn’t completed until it is confirmed via SMS—making it costly for bots to succeed undetected.
Trusted Access, On Demand
When a legitimate need arises for a second appointment, an authorised advisor can issue a dedicated scheduling link valid for one specific person—enabling secure, controlled follow-up bookings.
Detect, Shield, Serve
Suspicious behaviour is automatically detected and mitigated using backend and frontend telemetry, device fingerprinting, submission timing models, and behavioural analytics.
Together, these five layers can be adapted to build a strong defence that protects your booking system without compromising ease of access for citizens.
Fairness Is the Foundation
Each interaction a citizen has with public services either builds or erodes trust. When appointment slots become commodities sold in back channels, it’s not just an IT issue—it’s a challenge to public confidence.
By investing in secure, citizen-first scheduling systems like the TIMIFY Secure Citizen Scheduling Flow, institutions can:
Using a modern booking tool with automated workflows helps institutions save time and attract new clients by streamlining the scheduling process and reducing manual tasks.
Appointment scheduling may seem like a small process—but to your citizens, it reflects the values of the entire institution.
